La performance teatral del juglar contemporani Matteo Belli

En aquesta dissertació he intentat recórrer els principals elements que caracteritzen el treball teatral de l’actor contemporani bolonyès Matteo Belli. La primera part se centra en les informacions bàsiques, necessàries per col•locar correctament el fenòmen tan complex com fascinant del joglar. En segona instància, he pensat en aprofundir l’aspecte de la comicitat introduint directament el treball de Belli, i relacionar-lo, per dir-ho així, amb el panorama actual del teatre contemporani. A més a més, he presentat alguns exemples relacionats amb algunes obres d’artistes moderns i contemporanis italians, d’aquesta manera prentenc comprendre millor el procés de voluntarietat que s’amaga darrere la comicitat i els seus mecanismes intrínsecs. Per concloure, he inclòs una entrevista amb ell, que em va concedir en aquests quatre anys de recerca, on es pot apreciar, no només un gran coneixement del món de l’espectacle, sinó que també una profunda espessor cultural.

The Social contract with endogenous sentiments

Moral values infuence individual behavior and social interactions. A specially signif- cant instance is the case of moral values concerning work e¤ort. Individuals determine what they take to be proper behaviour and judge the others, and themselves, accordingly. They increase their esteem -and self-esteem- for those who perform in excess of the standard and decrease their esteem for those who work less. These changes in self-esteem result from the self-regulatory emotions of guilt or pride extensively studied in Social Psychology. We examine the interactions between sentiments, individual behaviour and the social contract in a model of rational voting over redistribution where individual self-esteem and relative es-teem for others are endogenously determined. Individuals di¤er in their productivities. The desired extent of redistribution depends both on individual income and on individual attitudes toward others. We characterize the politico-economic equilibria in which sentiments, labor supply and redistribution are simultaneously determined. The model has two types of equilibria. In "cohesive" equilibria, all individuals conform to the standard of proper behav- iour, income inequality is low and social esteem is not biased toward any particular type. Under these conditions equilibrium redistribution increases in response to larger inequality. In a "clustered" equilibrium skilled workers work above the mean while unskilled workers work below. In such an equilibrium, income inequality is large and sentiments are biased in favor of the industrious. As inequality increases, this bias may eventually overtake the egoistic demand for greater taxation and equilibrium redistribution decreases. The type of equilibrium that emerges crucially depends on inequality. We contrast the predictions of the model with data on inequality, redistribution, work values and attitudes toward work and toward the poor for a set of OECD countries.

El Evangelio según San Mateo : una adaptación cinematográfica de Pier Paolo

El Evangelio según San Mateo una adapatación cinematográfica de Pier Paolo Pasolini Este trabajo tiene tres partes, en la primera parte se describe la adaptación fílmica: mencionando diferentes clases de adaptaciones, tales como la adaptación fiel, la adaptación libre, la adaptación prestada y otros. Dando especial énfasis a la relación entre texto y obra cinematográfica, comparando sus distintas expresiones artísticas. En la segunda parte se presenta al poeta Pier Paolo Pasolini como cineasta, vislumbrando sus películas más importantes, analizando y exponiendo las diferentes etapas en su desarrollo como cineasta. El tercer capitulo se centra en la película “El Evangelio según San Mateo “de Pier Paolo Pasolini. Utilizando el guion de dicho director se compara su creación cinematográfica con el arte pictórico, facilitando a Pier Paolo Pasolini desarrollar un nuevo lenguaje cinematográfico, conocido como la sacralidad técnica.

Work values, endogenous sentiments and redistribution

We examine the interactions between individual behavior, sentiments and the social contract in a model of rational voting over redistribution. Agents have moral "work values". Individuals' self-esteem and social consideration of others are endogenously determined comparing behaviors to moral standards. Attitudes toward redistribution depend on self-interest and social preferences. We characterize the politico-economic equilibria in which sentiments, labor supply and redistribution are determined simultaneously. The equilibria feature different degrees of "social cohesion" and redistribution depending on pre-tax income inequality. In clustered equilibria the poor are held partly responsible for their low income since they work less than the moral standard and hence redistribution is low. The paper proposes a novel explanation for the emergence of different sentiments and social contracts across countries. The predictions appear broadly in line with well-documented differences between the United States and Europe.

On rigid analytic uniformizations of Jacobians of Shimura curves

The main goal of this article is to give an explicit rigid analytic uniformization of the maximal toric quotient of the Jacobian of a Shimura curve over Q at a prime dividing exactly the level. This result can be viewed as complementary to the classical theorem of Cerednik and Drinfeld which provides rigid analytic uniformizations at primes dividing the discriminant. As a corollary, we offer a proof of a conjecture formulated by M. Greenberg in hispaper on Stark-Heegner points and quaternionic Shimura curves, thus making Greenberg's construction of local points on elliptic curves over Q unconditional.

An irreducibility criterion for group representations, with arithmetic applications

We prove a criterion for the irreducibility of an integral group representation p over the fraction field of a noetherian domain R in terms of suitably defined reductions of p at prime ideals of R. As applications, we give irreducibility results for universal deformations of residual representations, with a special attention to universal deformations of residual Galois representations associated with modular forms of weight at least 2.

La poética del desig: amor i bogeria a l'Orlando furioso

Aquesta tesina, amb el títol "La poètica del desig. amor i bogeria a l'Orlando furioso", proposa una nova lectura del poema de Ludovico Ariosto, prenent com a objectiu l'anàlisi de la bogeria del seu protagonista, el Comte Orlando, "che per amor venne in furore e matto / d'uom che sì saggio era stimato prima". Així doncs, pretenem esbrinar per què davant de la constatació de Matteo Maria Boiardo d'un "Orlando innmorato", Ariosto va respondre amb un "Orlando furioso", narrant així "cosa non detta in prosa mai né in rima". Per arribar fins al fons de la qüestió, ens hem preguntat quins són l'origen, la manifestació textual, la dimensió i el significat del concepte de "furor" en el text; interrogants que ens han conduït cap a una bogeria amorosa que és manifestació externa d'un desig insatisfet. Un concepte que, a més a més d'evocar l"Hercules furens" d'Eurípides i Sèneca, ens remet a la teoria dels humors de Galè, al concepte de 'melancholia' d'Aristòtil i a l'eròtica platònica, al mateix temps que reprodueix els models del que Cesare Segre anomena la 'follie littéraire' característica de l'època medieval. A partir d'aquesta anàlisi s'ha interpretat el text com una apologia de les passions en la que es destrona al savi com a paradigma i model ètic, acabant així amb la imatge de l'home com a "animal rationale", situant per contra la seva "humanitas" ja no en la racionalitat (tampoc en la irracionalitat), sinó en la passionalitat, oferint així un retrat de l'ésser humà com a "animal passionalis" , una criatura intermitja en la que haurien de confluir idealment raó i passió.

Panel index VAR models: Specification, Estimation, Testing and Leading Indicators

This paper proposes a method to conduct inference in panel VAR models with cross unit interdependencies and time variations in the coefficients. The approach can be used to obtain multi-unit forecasts and leading indicators and to conduct policy analysis in a multiunit setups. The framework of analysis is Bayesian and MCMC methods are used to estimate the posterior distribution of the features of interest. The model is reparametrized to resemble an observable index model and specification searches are discussed. As an example, we construct leading indicators for inflation and GDP growth in the Euro area using G-7 information.

Similarities and convergence in G-7 cycles

This paper examines the properties of G-7 cycles using a multicountry Bayesian panelVAR model with time variations, unit specific dynamics and cross country interdependences.We demonstrate the presence of a significant world cycle and show that country specificindicators play a much smaller role. We detect differences across business cycle phasesbut, apart from an increase in synchronicity in the late 1990s, find little evidence of major structural changes. We also find no evidence of the existence of an Euro area specific cycle or of its emergence in the 1990s.

Estimating multi-country VAR models

This paper describes a methodology to estimate the coefficients, to test specification hypothesesand to conduct policy exercises in multi-country VAR models with cross unit interdependencies, unit specific dynamics and time variations in the coefficients. The framework of analysis is Bayesian: a prior flexibly reduces the dimensionality of the model and puts structure on the time variations; MCMC methods are used to obtain posterior distributions; and marginal likelihoods to check the fit of various specifications. Impulse responses and conditional forecasts are obtained with the output of MCMC routine. The transmission of certain shocks across countries is analyzed.

ClubMed? Cyclical fluctuations in the Mediterranean basin

We investigate macroeconomic fluctuations in the Mediterranean basin, their similarities and convergence. A model with four indicators, roughly covering theWest, the East and the Middle East and the North Africa portions of theMediterranean, characterizes well the historical experience since the early 1980.Idiosyncratic causes still dominate domestic cyclical fluctuations in many countries. Convergence and divergence coexist are local and transitory. The cyclicaloutlook for the next few years is rosier for the East than for the West.

Forecasting and turning point predictions in a Bayesian panel VAR model

We provide methods for forecasting variables and predicting turning points in panel Bayesian VARs. We specify a flexible model which accounts for both interdependencies in the cross section and time variations in the parameters. Posterior distributions for the parameters are obtained for a particular type of diffuse, for Minnesota-type and for hierarchical priors. Formulas for multistep, multiunit point and average forecasts are provided. An application to the problem of forecasting the growth rate of output and of predicting turning points in the G-7 illustrates the approach. A comparison with alternative forecasting methods is also provided.

Do institutional changes affect business cycles? Evidence from Europe

We study the effects that the Maastricht treaty, the creation of the ECB, andthe Euro changeover had on the dynamics of European business cycles using a panelVAR and data from ten European countries - seven from the Euro area and threeoutside of it. There are changes in the features of European business cycles and in thetransmission of shocks. They precede the three events of interest and are more linkedto a general process of European convergence and synchronization.

Nets: Network estimation for time series

This work proposes novel network analysis techniques for multivariate time series.We define the network of a multivariate time series as a graph where verticesdenote the components of the process and edges denote non zero long run partialcorrelations. We then introduce a two step LASSO procedure, called NETS, toestimate high dimensional sparse Long Run Partial Correlation networks. This approachis based on a VAR approximation of the process and allows to decomposethe long run linkages into the contribution of the dynamic and contemporaneousdependence relations of the system. The large sample properties of the estimatorare analysed and we establish conditions for consistent selection and estimation ofthe non zero long run partial correlations. The methodology is illustrated with anapplication to a panel of U.S. bluechips.
