La “ciudad arqueológica” en el área catalana ante la irrupción del Islam

Se presenta un breve estado de la cuestión sobre la realidad arqueológica de los principales núcleos urbanos del este de la provincia Tarraconensis y a finales del Regnum Gothorum. Existe un nivel de conocimiento desigual para estas ciudades, fruto del contexto actual de la investigación, y también de una evolución histórica diferenciada, como consecuencia de unas características geopolíticas propias que, posiblemente, indujeron a una modificación de las jerarquías entre las ciudades. Planteamos la ciudad visigoda como el centro de gestión civil y religioso de una unidad territorial donde la arqueología identifica los vestigios de la arquitectura del poder, pero todavía no consigue definir con precisión los procesos domésticos inherentes a toda comunidad urbana. Conocemos globalmente los diferentes procesos de la desestructuración urbana de la Antigüedad tardía pero no los parámetros de la ocupación agrourbana de los recintos amurallados. Para este período histórico se supone que la redimensión demográfica del hecho urbano más una reducción de las relaciones económicas entre la ciudad y el territorio son factores determinantes de las nuevas ciudades visigodas, pero se reconoce una incertidumbre fruto de la dificultad arqueológica de estudiar las nuevas pautas constructivas y una cultura material más restringida.

On games corresponding to sequencing situations with precedence relations

In this paper we study a class of cooperative sequencing games that arise from one-machine sequencing situations in which chain precedence relations are imposed on the jobs. It is shown that these sequencing games are convex.

Personal relations and their effect on behavior in an organizational setting: an experimental study

We study how personal relations affect performance in organizations. In the experimental game we use a manager has to assign different degrees of decision power to two employees. These two employees then have to make distributive decisions which affect themselves and the manager. Our focus is on the effects on managers' assignment of decision power and on employees' distributive decisions of one of the employees and the manager knowing each other personally. Our evidence shows that managers tend to favor employees that they personally know and that these employees tend, more than other employees, to favor the manager in their distributive decisions. However, this behavior does not affect the performance of the employees that do not know the manager. All these effects are independent of whether the employees that know the manager are more or less productive than those who do not know the manager. The results shed light on discrimination and nepotism and its consequences for the performance of family firms and other organizations.

The Politics of Intergovernmental Fiscal Relations in Argentina

The search for political determinants of intergovernmental fiscal relations has shaped much of the recent literature on the economic viability of federalism. This study assesses the explanatory power of two competing views about intergovernmental transfers; one emphasizing the traditional neoclassical approach to federal-subnational fiscal relations and the other suggesting that transfers are contingent on the political fortunes and current political vulnerability of each level of government. The author tests these models using data from Argentina, a federation exhibiting one of the most decentralised fiscal systems in the world and severe imbalances in the territorial distribution of legislative and economic resources. It is shown that overrespresented provinces ruled by governors who belong to opposition parties can bring into play their political overrepresentation to attract shares of federal transfers beyond social welfare criteria and to shield themselves from unwanted reforms to increase fiscal co-responsibilty. This finding suggests that decision makers in federal countries must pay close heed to the need to synchronize institutional reforms and fiscal adjustment.

Globalization and international relations: the Olympic Movement and European Integration

Essay elaborated by Shaelyne Johnson, undergraduate student of Global Studies at the University of California-Santa Barbara, during her internship at CEO-UAB for the academic course 2008/2009. She compares the organisational structure, goals and objectives of the institutions in the Olympic Movement and the European Integration, in order to find connections between both movements which were caused by globalization. The paper begins with an introduction of the changing world nowadays, followed by an overview on the structural similarities in the historical unfolding between these two parallel movements and, before concluding, new means for international relations are considered. This document is available in English through the digital library at the CEO-UAB Portal of Olympic Studies and the digital repository RECERCAT.

Les identitats de Hezbollah i la seva rellevància per a l'estudi de la cultura i la religió en les Relacions Internacionals

Aquest estudi analitza el paper de les identitats religiosa i de resistència en la transformació de Hezbollah i les seves relacions internacionals. Defensa que aquest moviment islàmic ha privilegiat interessos materials per sobre del dogma religiós quan ambdós factors no han coincidit. El marc teòric estudia les principals característiques de les interpretacions política i antropologista en la influència de la cultura i la religió en el comportament d’actors internacionals. El capítol dedicat a Hezbollah fa especial referència als nivells d’anàlisi nacional i regional. Pel que fa a la seva identitat religiosa, l’estudi conclou que el pragmatisme polític ha substituït les premisses panislàmiques pròpies dels orígens del moviment. També s’analitza la lluita contra Israel com a raó de ser de Hezbollah i s’argumenta que la identitat de resistència d’aquest moviment no ha sofert transformacions significatives al llarg del temps i s’ha combinat fàcilment amb la retòrica religiosa. La unió del marc teòric i l’estudi de cas permeten arribar a la conclusió que la concepció política de les identitats culturals i religioses en relacions internacionals esdevé la millor eina per a entendre l’evolució d’un actor com Hezbollah.

Hezbollah's identities and their relevance for cultural and religious IR

This working paper analyses the role of religious and resistance identities in Hezbollah’s transformation and foreign relations. It argues that this Islamist movement has privileged material concerns over the religious dogma when both factors have not been coincidental. To do so, it uses a theoretical framework that presents the main characteristics of the anthropological and political interpretations of the role of culture and religion in defining the behaviour of international actors. In the chapter dedicated to Hezbollah, close attention is paid to the domestic and regional levels of analysis. When assessing Hezbollah’s religious identity, this paper argues that the salience of the pan-Islamic religious identity in Hezbollah’s origins has been replaced by an increased political pragmatism. It also argues that the fight against Israel represents Hezbollah’s raison d’être and that its resistance identity has not suffered major transformations and has been easily combined with religious rhetoric. Linking Hezbollah’s case study with the theoretical framework, this paper argues that political conceptions of cultural and religious identities provide the best analytical tool to understand the evolution of this Islamist movement.

Modelling Interbank Relations during the International Financial Crisis

This paper examines the effects of the current financial crisis on the correlations of four international banking stocks. We find that in the beginning of the crisis banks generally show a transition to a higher correlation followed by a dramatic decline towards the end of 2008. These findings are consistent with both traditional contagion theory and the more recent network theory of contagion.
