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.

 

 

Global crop losses due to arthropods amount to 18-26% of the annual production. Efficient and sustainable pest control strategies are needed to reduce these losses. Many tools for controlling insect pests are available. Among them, biological control by insect natural enemies (predators and parasitoids) has recently gained renewed interest because of environmental concerns and problems encountered with the use of pesticides. Biological control has a long history of use in pest management and has been outstandingly successful in many instances. Nevertheless, such successes remain limited in number and failures are often under-reported. Moreover, biological control programs are still widely practiced as trial-and-error enterprises, rather than being guided by theory-driven principles.

The deficiency in theory-based biological control practices is not only due to insufficient basic information. A wealth of knowledge exists on the behavioral mechanisms employed by insect natural enemies to find and exploit their hosts/prey, as well as on their population dynamics and evolutionary adaptations to their environments. Moreover, a variety of modeling approaches are available to describe these processes and to predict their long-term population-level effects. These include tools such as static and dynamic optimization, game theory, stochastic dynamic modeling, matrix models and genetic algorithms. However, theoretical and empirical knowledge are often being advanced independently, limiting the interplay between the two fields and hence the connection between theory and practice.

Our study group will span the continuum between theoretical approaches (behavioral, population and community ecology) and application (biological control). Our main aim will be to bridge the existing gaps between the well-developed theory of interactions between insects and their natural enemies, and the optimization of the efficacy of biological control projects in agriculture and conservation. This interdisciplinary group will comprise mathematical biologists and experimentalists interested in close collaborations.
