The past fifty years have witnessed significant development in the study of the structure of urban centers. Dozens of cities in a variety of geographic regions and cultural environments have been studied, and their shape and society reconstructed.

Concurrently, the disciplines of urban archaeology, urban geography and urban history were defined and developed, enabling an integrated study of historical sources, archaeological remains and the analysis of geographic, architectural and regional data.

However, the theoretical interpretation of ancient and historic cities is still conditioned by the chronological and sociological paradigms established as far back as the 19th and early 20th centuries. Thus, for instance, the classification of cities into Eastern, i.e. "Oriental/Muslim/Middle or Far-Eastern" cities as opposed to "Occidental", i.e. European and North American ones is based, to a large extent, on the 19th century's neo-classical interpretation of historical economy. The accepted periodization of urban history into "Biblical", "Greek", "Roman", "Medieval" or "Early Modern" periods also reflects the ideologies, theologies and identities that created them. In many cases they are culturally or ethnically conditioned and cannot be justified outside of the specific culture that created them. Urban history is sufficiently complex and continuous to sustain different cultural definitions and different types of biased periodizations. As a result, the characterization of specifically defined types of cities such as "Muslim", "Medieval" or "greek" cities became almost self-evident, and the terms themselves, let alone the periodization that created them, was rarely contested.

In light of these conceptual paradigms, our research group will examine the processes of cultural, political, social and religious changes in both past and contemporary urban contexts. Adopting a multidisciplinary apprach and a wide chronological range, the members of the group will address an array of changes in urban structures, such as the formation of new centers of political might, structural changes of the public spaces, the creation of architectural icons, and the expansion and collapse of urban tissues, all in relation to major political, cultural and religious changes.

 

The goal of our research group is to examine the changing context of procedural, representative and liberal democracy in Latin America, analyze the contesting modes of democracy that have crystallized in the region, and evaluate their implications for a redefinition of citizenship models and alliances.

Latin America has long been a laboratory for comparative research. With its 20 independent polities, it provides a shared ground for systematic analysis into the resilience or breakdown of formal democracy against the background of contesting models of citizenship.

While in the days of the Cold War these models were relatively clear-cut and impacted on the region, generating the contrasting projects of reform and revolution, in the last two decades Latin America has witnessed both a renewal of democracy and the diversification of democratic experiments. The international presence of Venezuelan President Hugo Chávez, the election of an indigenous president in Bolivia and female presidents in Chile and Argentina, and recent policy decisions in Cuba, reflect the profound changes these countries have undergone, raising questions that are of far more than just regional interest.

Our research group brings together experts on various dimensions of citizenship in Latin America with a record in comparative research to reflect on the challenges affeting liberal democracies, as derived from the shift from corporatist to neo-liberal citizenship regimes; the increasing recognition of group rights and multiculturalism, evident with the potent rise of new indigenous movements; the emergence of participatory forms of anti-politics in situations of policy ineffectiveness and institutional collapse; the increasing use of plebiscitary democracy as a means of attaining political legitimacy; and the persistent challenge of mass citizen mobilization to existing forms of limited democracy.

 

 

Arabia (the Arabian Peninsula) may no longer be terra incognita, but many aspects of its history remain unknown. The study of the history and culture of this territory is still in its infancy. One of the difficulties in properly evaluating the historical evidence about the ancient Near East is that modern Europeans or westerners approaching it inevitably do it with a host of confused and half-formed preconceptions about the "Orient", as Fergus Millar has noted in his book The Roman Near East 31 BC - AD 337.

In the last three decades an ever growing amount of new archaeological data, including a wealth of new inscriptions in many languages and scripts (Akkadian, Aramaic, Nabataean and South Arabian) has been gathered from sites in Saudi Arabia, the Yemen, the Persian Gulf, Sinai, the Negev, Jordan and Syria, as well as from sites of the cultures bordering with Arabia. Moreover, many texts in classical Arabic are now more accessible than ever before through various electronic media.

The group will evaluate the state of our knowledge about Arabia and the prospects for future research.

 

 

Contemporary critical theory, which highlights the creative dimension of the reading process, is increasingly reorienting the study of the history of scriptural interpretation, situating it within the flux of literary and cultural movements at large. This international research group brings together scholars of Jewish, Christian and Muslim interpretation to conduct a close comparative analysis of shifting encounters with Scripture in three overlapping cultures. Drawing upon diverse yet complimentary perspectives, the participants in this group will investigate five fundamental subjects:

a. The critical role that interpretation played in the formation of Sacred Scripture;

b. Changing conceptions of the "plain sense" of Scripture;

c. The ways in which classical rhetoric and poetics informed scriptural interpretation;

d. Tensions created by the need to transplant Scripture into new linguistic media;

e. The ways in which the Bible has been reconfigured in literature, art and scholarship.

 

 

This research group will explore new and important developments in Category theory, Topology, Representation theory and Physics.

 

The last decade has seen the emergence and growth of a new interdisciplinary field of research often termed "Algorithmic Game Theory". This field lies at the crossroads of computer science, game theory, and economics; a combination which is necessary for addressing many of the challenges posed by the Internet. Not only is this field full of intellectual excitement internally, and not only has it already begun to intellectually influence the three parent disciplines, but it also has significant implications for the Internet, as evidenced by the large number of researchers in the field hired by Google, Yahoo, and Microsoft.

At the approximate age of ten years, it seems that the field of Algorithmic Game Theory is maturing. The goal of this group is to elucidate the main challenges of the field and attempt to chart the future course of the field for the next decade.

Some research topics that will be explored:

- Networks with contagious risk, the different aspects of how the evaluation of the Generalized Second Price mechanisms are used for selling ads on the Internet, and the understanding of the performance of simple auctions and modeling auctions used in practice (Eva Tardos)

- Interviewing in stable matching problems and cost-sharing mechanisms (Nicole Immorlica)

- Sketching valuation functions, the equilibria of simple market mechanisms, and optimal multi-item auctions (Noam Nisan)

- Auction design for agents with uncertain, private values (Anna Karlin)

- A general framework for computing optimal correlated equilibria in compact games, computing Nash equilibria of action-graph games via support enumeration, mechanical design and auctions, and computational equilibrium analysis of voting games (Kevin Leyton-Brown)

- Envy-free mechanisms for multiunit auctions with budgets, cost sharing games with capacitated network links, and game theoretic perspectives of the facility location problem (Michal Feldman)

- Bargaining in networks (Amos Fiat)
