In an era of globalization and massive institutional change in the international community, developing a workable set of ideas about global or international justice is one of the most important tasks facing philosophers, political theorists, lawyers and economics. Current events raise imperative political and moral questios concerning the moral standing of states and ethnocultural communities, states' rights against interventional in their internal affairs, their right to use force to protect their territorial integrity, and their right to protect their citizens or to protect citizens of other states.

Similarly, the growing interdependence among states introduces an entire set of concerns regarding global distributive justice, whereas the histories of relationships among states (colonialism, wars, secessions, etc.) suggest concerns regarding global corrective justice. These questions focus on the duties of affluent states to aid poor countries and refugees, the duties of colonial states to compensate their former colonies, the just treatment of statelessness and the just distribution of cultural rights, citizenship, residency, wealth, and the world's natural resources. These ample practical applications of global justice are what make it one of the most viable and increasingly important subfields of political philosophy.

Some of the most fundamental themes of global justice have been widely discussed in the context of just war theory. 

The research group will study three areas:

(1) The morality of the laws of war, with special attention to the institutional arrangements recommended by the statist and the cosmopolitan competing theories of just wars

(2) The statist and cosmopolitan theories of global justice, mainly distributive, but also corrective

(3) How debates between statists and cosmopolitans in these two fields -- international justice and just war theory -- are related, and how morality and the laws of war are implemented in the different conceptions of international justice.

 

 

International criminal law (ICL) is a unique branch of law, as it addresses the gravest crimes of concern to the international community as a whole through the imposition of criminal responsibility directly upon individuals (rather than upon states). ICL has become more prominent in recent years. New institutions have been created (most notably, the International Criminal Court [ICC]) and a growing number of international norms have penetrated national laws and are now applied more frequently by national courts (e.g., through the universal jurisdiction doctrine). Still, the theoretic basis of international criminal law is weak and its relationship to national criminal law is less than clear.

The aim of the research group is to examine closely the development of criminal law principles and basic notions in order to evaluate the process of migration of criminal law norms from national to international law. Our hope is that the research will provide a better understanding of the potential and shortcomings of international criminal law at the beginning of the 21st century, and serve as the basis for normative and institutional proposal reforms.

 

Theoretical and practical rationality are concerned with reasons, and aim to respond to normative questions: "What ought one to believe?" and "What should one do?". Theoretical rationality answers its questions by assessing and weighing reasons for beliefe and the (internal) relations among the beliefs. Arguably, theoretical reason aims at the truth of propositions. Accordingly, reasons for belief are considerations that speak in favour of propositions being worthy of acceptance insofar as one's aim in belief is the truth.

The reasons which practical rationality invokes are considerations that speak in favour of performing particular actions or adopting particular intentions and ends. And the internal relationships it appeals to are thos between means and ends on the one hand, and intentions and actions on the other.

Philosophers have always studied theoretical and practical rationality, and both topics continue to present vexing and philosophically significant questions. Many suggestive comparisons and distinctions between the two can be found in the philosophical literature. However, these insights are usually random and piecemeal; a sustained study of the relationships and differences between the two kinds of rationality is rarely conducted. Our aim is to study the similarities and differences between the two areas in a systematic way, so as to apply insights gleaned from one realm to the other, and gain a better understanding of the relationship between them and of the nature of reason in general.

 

 

During the Middle Ages, in Christian Europe, the religious and linguistic borders between Jews and the surrounding Christian culture always remained less permeable than those in Muslim countries, and very little knowledge was appropriated from the neighbouring Scholastic Christian culture. in the Midi (the southern area of contemporary France) hardly any philosophical or scientific works were translated from Latin into Hebrew. One could perhaps even go so far as to speak of a "Latino-phobic attitude on the part of medieval Jews of the Midi in general.

However, the field of medicine is an exception to this generalization. As far back as the 12th century, and again in the 14th and the 15th, scores of medical works were translated from Latin into Hebrew. Jewish and Christian doctors frequently cooperated with each other and treated patients together. Our research group is focusing on the macro-phenomenon of the role played by medieval doctors in bringing about a cultural transfer from Latin into Hebrew cultures, or from Christians to Jews.

Doctors hold a singular position within the social system of knowledge, since all members of all religions and cultures have similarly constructed human bodes, and all human beings, regardless of their religious and cultural backgrounds, suffer from similar illnesses and seek to be healed from these illnesses. Patients always attempt to seek out the best possible medical treatment, thus putting the Jewish doctors in constant and direct competition with the environing non-Jewish health system. Therefore, medicine was usually a unified knowledge system in which Jewish doctors were compelled to keep up with the tendencies of medicine in the host societies and "modernize".

The study of the history of "Medicine and the Jews" as part of the development of Jewish culture in its Christian European environment is much more than the study of the appropriation of professional and scientific knowledge by one specific socio-religious group. It is rather a comprehensive enquiry into the catalytic role Jewish physicians played in the processes of change which Jewish cultures underwent in southern Europe during the Middle Ages.

 

The classical model in economic theory assumes that the economic agent is fully rational. In particular, it is assumed that the agent is aware of the set of actions that is available to him and has a correct model of the environment in which he is operating. In particular, he understands the relationship between his actions and outcomes. Any calculation or consideration that is relevant to achieve this complete understanding of the environment can be done without mistake, with no delay, and without cost. In addition, the agent has a complete and consistent preference over the set of possible outcomes and chooses the action that leads to the best outcome with respect to his preference.

This model is clearly unrealistic. A human agent is often unaware of actions, contingencies, and considerations that are relevant for the decision problem that he is facing. He often finds it difficult to form a preference (for example, to determine his trade-off between price and quality, or the trade-off between current pleasure and future welfare), and there are specific limits on his ability to process information (specifically, attention, memory, and thinking are bounded and costly). Economists have of course realized that people are subject to these limitations; however, until they were exposed to the research in cognitive psychology they did not have a concrete sense of the systematic deviations of human decision making from the rational model.

The research agenda of our group consists of two main components:

(1) Studying models of decision making that depart from the standard model and in particular take into account cognitive limitations and non-standard preferences.

(2) Studying the implications of bounded rationality in multi-person interactions, in particular, games and market economics.

 

 

The focus of the group is on a currently intensively-studied model in theoretical physics, which has been termed by some the "hydrogen atom of the 21st century". The basic idea and goal was to construct a mathematically exact solution of an, admittedly idealized, quantum field theory of the general type as occurs in the description of the forces between our universe's elementary particles, with the notable exception of the gravitational force.

Yang-Mills gauge theory is named for its inventors, Chen Ning Yang and Robert Mills. The word gauge refers to the fact that at the heart of these theories lies a certain built-in redundancy in its mathematical description very hard to eliminate, while apparently necessary in order to properly record and understand the rules of the game. The idealized system at the focus of our group is called N=4 super Yang-Mills gauge theory. It stipulates that in addition to our standard continuous ("bosonic") spacetime dimensions, certain hidden discrete ("fermionic") dimensions exist. The number N=4 refers to the fact that this model has four such curious symmetries.

The N=4 gauge model is the most beautiful and simplest Yang-Mills theory one can come up with, even though it certainly does not directly appear in nature. It is also a deeply mysterious model, and it has become clear in recent years that it possesses further hidden symmetries as well as seemingly contradictory, alternative descriptions, which promise to allow for a complete solution of the model, at least for certain quantities and in certain limits. This is precisely what we are setting out to achieve with our program at the IIAS.

 

Molecular electronics, one of the major fields in nanoscience, studies electronic devices based on single molecules, and on molecular networks connected to other electronic components. Its potential applications include sensors, displays, smart materials, molecular motors, logic and memory devices, molecular scale transistors and energy transduction devices. Besides being the next step in device miniaturization, molecules are able to bind to one another, recognize each other, assemble into larger structures, and exhibit dynamical stereochemistry. In addition to its technological potential, molecular electronics has raised many new fundamental questions, e.g. concerning the interactions of molecular systems with their environment and their functioning far from equilibrium.  Also, fluctuations and noise constitute an important part of the physics of such microscopic systems. At the moment there already exist several ingenious experimental realizations of transport through molecular bridges. There also exist a variety of different theoretical tools (both in chemistry and in physics) to attack the above important issues.

This group will bring together physicists and chemists, experimentalists and theoreticians, senior and young scientists, aiming to understand existing experiments, to propose new experiments (possibly combining various experimental tools) and new technological devices, using combinations of  various theoretical and experimental methods.

 

Throughout Western history women have been assigned a status as cultural observers and social facilitators to men's roles as cultural performers and social actors. This status however, was not fixed, and cultural-social gender barriers could be crossed. Authority in the family, responsibilities in the public sphere, communal activism, economic productivity, education, ritual religious roles, literary and artistic creativity were all forms of cultural capital which could position women at intersections of power and privilege and challenge gender hierarchies. Recent decades have witnessed a revolution in the scholarship of women's history, uncovering trends that complicate accounts of the possibilities for women. However, these investigations into women’s social and cultural roles have been based predominantly on the lives of Christian women, in Europe west of the Oder, and in North America. A primary research objective of our group is to turn to communities that, both geographically and culturally, have not been properly attended to by the existing scholarship. By bringing together a group of scholars who specialize in a range of periods and locations, our research will create a framework for exploring these issues in Jewish history and their implications for other histories of women.

 

The Book of Genesis and the beginning of the Book of Exodus are of utmost importance for many fundamental issues in the study of Judaism, Christianity, and nascent Islam. The traditions related to the narrative passages of these books refer, inter alia, to the Creation of the World, Adam as bearer of God's image, angels and demons, Enoch, Divine election, the covenants with the patriarchs prior to Sinai, the establishment of monotheism, the formation of Israel as a nation, and the Exodus. These themes were highly significant in the formulation of the competing religious worldviews and self-understanding of Second Temple and rabbinic Judaism, early Christianity, Gnosticism, and eventually early Islam. It should be emphasized that the relevant material is not confined to works dedicated expressly to the exegesis of these biblical books; rather, themes of Genesis and the beginning of Exodus are part and parcel of the religious messages of Jewish, Christian and nascent Islamic thought.

Themes and traditions from Genesis and Exodus may be found in a vast array of sources in Antiquity. The Qur'an – unlike medieval Islamic traditions – is one of the latest products of Late Antiquity. While scholarship by and large has tended toward the study of the relevant biblical themes in each religion unto itself, comparative studies transcending the boundaries between the corpora of varying religious traditions are often mutually illuminating. The group’s purpose is not merely to map and compare divergent traditions, but also to elucidate the dynamics of transformation among them, considering the relationships (including polemics and influence) among the religious groups of Antiquity. The anticipated collaboration of scholars from diverse backgrounds in the proposed Research Group will be a rare opportunity for productive synergy.
 

 

We propose to study the general problems of functionality and robustness in complex biological systems, through a focus on the adaptive immune response as a model system. The adaptive immune response is a complex system, which comprises many interacting cells that are subject to various sources of stochasticity. We will address fundamental questions in the field such as how B and T cell repertoires collectively go through a process of stochastic diversity generation and clonal selection, and consistently yield functional controlled immune responses in a noisy environment. This understanding will be important in developing control strategies to modulate the immune response (e.g., with vaccinations or immune therapies) since, while predictable in the aggregate, human immune responses can display marked variability. For example, a small fraction of individuals do not raise antibodies following influenza vaccination, and efficacy rates for vaccination in older individuals are generally under 30%. Infections with West Nile virus are usually asymptomatic, but some patients experience severe neurological disease and even death. The potential role of stochasticity at different spatial and temporal scales in driving these diverse yet robus responses will be a main focus of our research group.

It is often said that criminal law faces a crisis of legitimacy: a crisis of perceived legitimacy, in that many of those who are subject to it do not regard it as author- itative; a crisis of normative legitimacy, insofar as it cannot plausibly claim the authority that it needs.

This Research Group will pursue five lines of research aimed at understanding and finding ways of responding to it. First, we take seriously the fact that criminal law is a political institution, whose legitimation must be grounded in political theory. Second, we will explore the ways in which criminal law can be differentiated from other legal and extra-legal mechanisms for regulating behavior. Third, we will examine the scope of activities that can legitimately be criminalized, since a failure to honor appropriate limitations on that scope is another source of the crisis of legitimacy. Fourth, we will examine the procedural features that are necessary for strengthening the legitimacy of criminal law. Finally, we will attend to criminal punishment, in particular the question of what modes of criminal punishment can play a legitimate role in a democratic polity. 

 

Our Research Group aims to develop a general theory that provides novel, mechanistic understandings of the ways in which environmental changes regulate ecosystem processes via alteration of an animal's trophic functions.

We suggest using stress physiology as a common mechanism to scale plasticity in energy and elemental budgets at the individual level to processes occurring at the population, community and ecosystem levels. Trait expressions are shaped by evolution and are constrained by conservative biological processes. Thus, this evolutionary-based framework has much potential to reveal how ecological interactions emerge across levels of biological organization, and may assist in unifying existing, currently separated theories. Such an understanding is also crucial to better predict how human-induced rapid environmental changes will affect life-supporting ecosystem services. 

 

Astronomy is in the midst of a transformation brought on by exponentially progressing technological advances in the information age. New detector capabilities and faster computation have created a new era in which the use of advanced data mining and inference methods could bring new answers to long-standing scientific questions. The proposed research group, which includes leading figures in data analysis of exo-planets will 

• prepare algorithms for analysis of data from the forthcoming TESS space mission, 

• apply Gaussian Processes and machine learning algorithms to model stellar variability in transit and radial-velocity studies of exo-planets, and 

• study exo-planetary system architectures by developing population models and confront them with the accumulating data, using new statistical tools. 

We expect the research group to provide a better understanding of the exo-planetary population via advanced statistical tools — a giant leap in one of the most exciting fields of present science. 

 

The purpose of the research group is to investigate: the reception, followed by the naturalization, of Aristotelian logic into medieval Jewish cultures in Europe; and the repercussions of the introduction of logic into the Jewish intellectual matrix in numerous other areas of Jewish thought, beyond the field of logic itself. The proposed group will bring together scholars from various corners of medieval intellectual history: two historians of logic (specializing in the history of logic in Hebrew and Arabic); historians of medieval science, medicine, and philosophy; and scholars who study medieval religious polemic and Biblical exegesis, with an emphasis on the use of logic therein. Among the questions to be considered will be: What was the place of logic in the overall transfer of rationalist philosophical/scientific culture to European Jews in the Middle Ages (12th-15th centuries)? How did the study of logic affect intellectual activity in various areas, including traditional Jewish subjects (e.g. religious polemics; medicine; biblical exegesis; Talmud study).

By highlighting the interdisciplinary importance of medieval logic in Hebrew, we anticipate that the impact of this group will extend beyond the history of medieval philosophy, into the fields of general European medieval culture and history, Christian intellectual history, history of philosophy and logic, history of medicine, kabbalah, etc. We hope to bring to the attention of scholars of Jewish intellectual history and historians of logic just how widespread the study of logic by Jews in the Middle Ages was, and how it impacted their other intellectual endeavors.

 

 

This project aims to shed light on a dark corner in history, which was surprisingly very little investigated until now: how was it that the unit of ‘day’ and its primary division into 12 ‘hours’ came to ne conceived in human culture? The division seems to have been gradually developed in ancient Egypt and then migrated also to cuneiform sources from Mesopotamia. It then circulated, not quite smoothly, into the Greek world and subsequently into western late antique and medieval culture. This account remains vague because there is no comprehensive and solid research that could clarify it more pointedly.

New concepts of the division of the day required proper technological means to express them. After tracing this historical riddle, however, a lot remains to be explored for subsequent periods in history. We ask how the science and technologies of time measurement determined the structure and division of the day unit, conceptually as well as in practice, and conversely, to what extent did conceptual and practical divisions of the day unit underpin and influence the development of time measurement technologies. Time is in many ways a human construction, which requires a set of rituals and cultural agents in order to reinforce it. We aim to study these various mechanisms.

The suggested team is a unique combination of experts for the history of time in their respective fields. Such a group has never before been assembled to study this type of question. The group consists of historians of science and technology as well as of law and of religious and cultural institutions. The historical periods and geographical spread covered by the group is exceptionally wide: from ancient Mesopotamia and Egypt, to ancient Jewish culture (Second Temple, rabbinic) and into Medieval Judaism, Greek and Roman history, Islamic culture, and the literature of medieval Ethiopia.
