Le but de cette these est une introduction a une lecture pertinente, au xxeme siecle, de l'oeuvre de Francis Ponge et une situation de cette oeuvre par rapport a differents domaines de notre culture contemporaine : sciences (physique, mathematique) et arts (peinture, musique). Elle s'appuie, pour ce faire, sur des recherches propres a la litterature et a la critique litteraire mais aussi, de facon plus large, sur des travaux d'epistemologie: La raison et la passion (de Jean Hamburger) Ethnologie: race et histoire (de Claude Levi-Strauss), de philosophie, L'ironie (de Vladimir Jankelevich), de semiologie: La leçon (de Roland Barthes) ou L'oeuvre ouverte (d'Umberto Eco), le principal sujet de ces approches a plusieurs voix etant, avant tout, le langage et les fascinantes questions de lecture, ecriture, pouvoir, savoir, autoreference, mises en oeuvre de facon exemplaire dans les textes de Francis Ponge. Ce langage "en pieces" et les questions qui lui sont liees requierent en effet, de la part du lecteur, la mise en oeuvre, en retour, d'un certain nombre de stratagemes et strategies auxquels cette these voudrait en quelque sorte l'initier et l'exercer pour lui permettre d'aborder alors, dans les meilleures conditions possibles, l'oeuvre de Francis Ponge, entre autres. La these n'est donc pas un "pour un Ponge" au sens ou Ponge a ecrit "pour un Malherbe": il ne s'agit pas de faire ici l'apologie d'une oeuvre dont elle montre d'ailleurs, aussi, les limites. Si "pour" il y a c'est un "pour" mode d'emploi, une invitation au voyage, une experience d'alterite qui explique egalement le recours au roman de Kane (Cheik Hamidou) : l'aventure ambigue et les nombreuses illustrations et citations qui caracterisent ce travail<br>The purpose of this thesis is a preparatory introduction to a pertinent reading, in the 20th century, of francis ponge's work and its place in the different sphares of our contempory culture: sciences (physics, mathematics) and arts (painting, music). It is based on research proper to literature and literary criticism but, also, in a broader way, to works of epistemology: reason and passion (by jean hamburger), ethnology: race and history (by claude levi-strauss), philosophy: the irony (by vladimir jankelevich); semiology: the lesson (by roland barthes) or the open work (by umberto eco), the chief subject of these approaches which cover different fields being above all, the language and the fascinating questions about reading, writing, power, knowledge, autoreference. . . Brought into play in an exemplary way by francis ponge's texts. This language in a composite form and the questions linked to it, require the reader to bring into play, in return, a good many stratagems and strategies to which this thesis wants, in some way to initiate and help him to approach francis ponge's work, in the best conditions. This thesis is not a "for a ponge" in the meaning in which ponge wrote "for a malherbe": the question is not here to vindicate a work the limits of which morever it demonstrates; if "for" there is it's the "for" of "directions for use" on invitation to travel, an experience of alterity that also explains the recourse to cheik hamidou kane's novel: the ambiguous adventure and the numerous illustrations and quotations that characterize this thesis

En este trabajo se analiza el discurso de los programas de la administración pública federal del sexenio del Dr. Ernesto Zedillo Ponce de león al sexenio del Lic. Vicente Fox Quesada. Al trabajo le guían las siguientes interrogantes ¿en base a la Nueva Gestión Pública, qué cambios operaron en los programas de la Administración Pública? ¿Fueron de forma o de fondo, en que consistieron? ¿O solo existe continuidad entre ambos sexenios?

This three-paper dissertation aims to contribute to the study of the Mexican presidency, in particular, to the understanding of the origins and use of presidential polling, its role in the policy activity of the president, and the dynamics of presidential approval between 1989 and 2011. The dissertation draws upon the presidential polling, opinion-policy and approval research done in the United States. The first paper explores a topic that has not received much attention in Mexico, the origins and use of the presidential polling unit (PPU). The second paper focuses on presidential approval in Mexico, and the third analyzes, yet another understudied topic, the relationship between government spending (used as proxy for policy) and public opinion (collected by the PPU). The first paper relies on crosstabulations, text analysis, wordclouds and cluster analysis. Additionally, to offer an insider's view, I conducted a series of interviews to seven presidential staffers during the administrations of Presidents Carlos Salinas de Gortari (Dec/1988-Nov/1994), Ernesto Zedillo Ponce de León (Dec/1994-Nov/2000), and Vicente Fox Quezada (Dec/2000-Nov/2006). The second and third papers made use of vector autoregression models to account for feedback effects among the spending and opinion variables, controlling, at the same time, for a possible `backwards' process in the opinion variables. The main assumption is that the variables are connected: all variables depend and/or explain each other.The first paper entitled "Origins and Use of Presidential Polling in Mexico" addresses the questions of what caused the creation of a government office dedicated to gauge public opinion, what poll information the presidents collected, and how it was used. I will argue that the institutionalization of public opinion within the presidency responded to the dynamics of the political system, in particular, to the changes in the electoral system and the outcome of the presidential election of 1988. The election of 1988 changed Mexico's electoral map and reconfigured the party loyalties against the ruling party PRI. Aware of this new political context, President Salinas used polling not only to study the political behavior of the Mexican voters but also as an alternative to verify electoral results. In fact, the first mandate of the presidential polling unit was to track political preferences. Eventually the use of public opinion polls expanded to other issues and became part of the presidential policy toolkit. As Jacobs and Shapiro (1995) pointed out in the case of the Kennedy administration, the Mexican presidency had now an office with "routinized procedures" to research and collect public opinion data. To identify the type of polling information collected by the presidents, in addition to interviews to presidential staffers, I applied text analysis on titles of all presidential polls conducted between 1989 and 2006. While all presidents collected opinion data on their approval ratings and customized their polling operations according to their own policy agenda, there were some overall differences. President Salinas centered his field polling operations around policy, and his phone polls for elections and presidential image. President Zedillo used field polls mostly for electoral issues and phone polls for image and communications. President Fox focused the field polls for government evaluation and customer satisfaction, and his phone polls for image and evaluation of political figures. How public opinion information was used remains an open chapter. All presidential insiders mentioned that information from public opinion polls was not specifically used to design policy but rather to test it, and to see what worked and what did not work. Polling was used to find ways to convince the public of the benefits of the presidential policies and actions. From this analysis, the conclusion is similar to what Jacobs (1992) argued in his paper on recoil effect. The presidents did use polling to try to move public opinion to their side, but also polling was used to understand what was in the mind of the public. Eventually, these efforts, I believe, made a significant contribution to the development of political public opinion and, most importantly, to the development of democratic values among the political elites.The second paper entitled "Presidential Approval in Mexico" looks at the factors that influence presidential approval using as reference research done in the United States and Mexico. I am looking for evidence that presidential approval in Mexico depends on factors directly connected to policy outcomes (Erikson, MacKuen and Stimson 2002). The risk of manipulation is at the center of this connection. The president may create the illusion of meeting the public's expectations (Kernel 1997) and/or opinion elites may misled the public against the president (MacKuen, Erikson and Stimson 1992). The argument here is that as long as presidential popularity is rooted in objective measures related to policy or economic outcomes, approval may actually be a reliable indicator of citizen's response to government actions and, therefore, a reliable measure of the president's political capital. Thus, the research question is whether approval depends on objective measures of the economy (and the overall situation of the country) or relies on the public's perceptions about the current conditions of the country. Furthermore, are those perceptions retrospective or prospective? Do they rely on what has been done or what is expected to be done? The findings presented in this paper confirm the expectations that the popularity of the Mexican president depends mostly on how the economy is doing and how the president deals with current salient issues like public safety (Buendia 1996; Gómez-Vilchis 2012). At the level of perceptions, prospective evaluations of personal well-being have a positive impact on approval but only among the richer segments of the population. It is important to notice that these perceptions are strongly influenced by the unemployment rates. The overall conclusion is that presidential approval in Mexico is rooted in macroeconomic, salient and subjective measures that are also connected to the dynamics of leading economic indicators. Presidential approval in Mexico depends, so far, on the president's capacity to solve problems.The third paper entitled "Government spending and public opinion in Mexico" explores the relationship between policy and public opinion. While this paper draws upon the opinion-policy research done in the United States, it departs from the policy preference approach to a perspective centered on policy outcomes. The main opinion variables included in the models refer to retrospective and prospective evaluations of personal well-being. These are generic and, in the question wording, do not refer to any issue in particular. One of the goals is to find whether these opinion variables are directly connected to trends in leading economic indicators (like growth of GDP percapita, unemployment, inflation). If such connection exists, then they may represent citizen's responses to current state of affairs of which the president and the government in general are perceived as responsible. This is, the opinion variables can be taken as responding to policy outcomes. The main underlying logic follows the Mood and Thermostatic models suggested by Erikson, MacKuen and Stimson (2002) and Soroka and Welzien (2010) respectively. If people started to feel that things are getting worse, then I would expect the government to increase spending, for example to stimulate the economy. Conversely, if people feel things are getting better, then I would expect the president to scale back on spending. The models show feedback in the economic but not in the public safety models (this is, the reciprocal effect between opinion and spending). In the models where economic spending is the contemporaneous outcome variable, positive prospective evaluations of personal well-being and perceptions that the economy is the most important problem (MIP) facing the nation show significant effects on spending. In the case of spending on public safety, negative prospective evaluation of personal well-being and the perceptions that public safety is the most important problem in the country play a significant role (but there is no feedback). An important finding is that the public attentiveness to economic issues (MIP) does explain a significant portion of the variance in spending on the economy. Regarding the impact of opinions by socioeconomic status, there is not enough evidence to conclude that the President listens more to a particular segment of the population. The results, however, seem to indicate a marginal difference in favor of the public with lower income and education levels. Overall, the findings presented here show a connection between presidential spending activity and public opinion. This suggests some responsiveness towards public opinion. Regardless of their own personal agendas, presidents have worked to improve the conditions of the citizens and responded to their perceptions of the general situation of the country. The fact that most of the population is still poor combined with the fact that polling is here to stay (along with the new impact of social media), has forced politicians to be responsive to the needs and wants of the public. As long as the public remains connected to its economic reality and pay attention to their immediate environment, any attempt of manipulation will not last long. The Mexican public is wise and, repeatedly in electoral processes, it has demonstrated strong and reasonable political culture. Mexican politicians are catching up with the public and this is a good thing. However, as democracy consolidates in Mexico, it may be possible to see the nature of responsiveness changing as the influence of traditional political elites fades and other forms of influence start taking over. Mexico is still in a democratic honeymoon.

El trabajo examina los incentivos fiscales introducidos de manera generalizada por las comunidades autónomas de régimen común en los tributos cedidos con la intención de frenar (o revertir) la despoblación de las áreas rurales. Específicamente, se pone el foco sobre la Comunidad Autónoma de Castilla y León y, con base en el Panel de Declarantes del IRPF, se analiza la utilización a lo largo del tiempo por sus contribuyentes de las deducciones por adquisición o rehabilitación de vivienda habitual y por nacimiento o adopción de hijos, ambas en núcleos rurales. Los resultados obtenidos permiten concluir que, en los períodos considerados, se ha producido un cierto traslado de la población a núcleos rurales, proveniente, en buena medida, de capitales de provincia de la misma Comunidad, y con cierta vocación de permanencia, ya que casi todos los desplazados a un pequeño municipio (y también los que han disfrutado de las deducciones sin haber cambiado su residencia) siguen viviendo en el mismo al final de los períodos contemplados.

En esta ponencia vamos a hablar de varias investigaciones del grupo Arte y Memoria que surgió en el Campus de Teruel de la Universidad de Zaragoza en el año 2009, por el interés de conservar la memoria, y, del arte como soporte de la memoria, y, como mecanismo de conservación del legado cultural (patrimonio), debido a que el arte, la memoria y el patrimonio van de la mano. Ya que, el arte es el lugar de la memoria y está construido con ella y el patrimonio es el testigo de la memoria. Lejos de presentar una única visión de un fenómeno tan complejo, se opta por dar cabida a distintas miradas y distintos enfoques. Por lo que, el desarrollo de nuestras investigaciones está basado en un enfoque multidisciplinar que pone de manifiesto la complejidad de las relaciones entre, las producciones artísticas, la memoria y el legado cultural, mostrando, de forma poliédrica, las múltiples propuestas teóricas que van acercando estos temas desde las distintas disciplinas que lo estudian. Por ser un fenómeno complejo, no se pretende dirigir el objeto mismo de la investigación hacia unas conclusiones cerradas, sino, más bien, de abrirnos a la complejidad que adopta este tema en sus múltiples dimensiones y combinaciones posibles con el arte contemporáneo y el legado cultural. El grupo está conformado por colaboradores de diferentes universidades [Universidad de Zaragoza, Universidad Complutense de Madrid, Universitè Stendal- Grenoble III (Francia), University at Albany State University of New York (SUNY), Universidad Nacional Autónoma de México (UNAM), Universidad de Ibague (Colombia), Accademia di Belle Arti diVenezia ]; por destacados/as profesionales de la comunidad aragonesa (arquitectos, ingenieros, artistas) por gestores culturales ( de Aragón, de Castilla y León , del Principado de Asturias y del Instituto Cervantes de Madrid).
