Some applications are displayed: these include a Galois cohomological descent spectral sequence for the étale K–theory of a scheme (where the Galois group is the Grothendieck fundamental group), and the Morel–Voevodsky description of Thomason–Trobaugh K–theory as Nisnevich K–theory in nonnegative degrees. The is also a spectrum-level description of Voevodsky’s periodicity operator for Nisnevich...

We examine a certain modal consequence relation, and define the notion of validity of a modal sequent on a frame. We demonstrate that it is possible to define classes of frames. not definable by modal formulas, by modal sequents. Through the use of modal algebras and general frames, we obtain a characterization of modal sequent-definable classes of frames which are also first-order definable, a...

World War I irrevocably changed the face of the world, including Croatia and its capital Zagreb. While between 1880 and 1910 Zagreb became a modern European city, World War I (1914-1918) was marked by new municipal regulations that overturned the everyday life of the city. Social conditions reached catastrophic proportions, especially in the later years of the war. Soldiers and refugees swarmed...

In the Middle East, the military dimension of the ArabIsraeli conflict remains prominent. Without an agreement by Israel to withdraw peacefully from the Golan Heights, which it has occupied since the 1967 war, or from the zone in southern Lebanon it has controlled since 1978, another war between Syria and Israel is possible. Syrian leaders regard the Israeli occupation of both areas as an affro...

SUMMARY After a short reference to Iran-Iraq war as a motivating factor for the present study, the issues of battle stress and psychological wounds of war ar discuused. Reactions of the world armies 10 psychological breakdown of soldiers, military psychotherapy, therapy in combat zone and its developmental process through Civil war, Crimean war, first and Second world wars, Korean and Vietnam ...

I propose an evolutionary psychological perspective on wars and suggest that the ultimate cause of intergroup conflict may be the relative availability of reproductive women. Polygyny, which allows some men to monopolize all reproductive opportunities and exclude others, may increase the prevalence of civil wars, but not interstate wars, which did not exist in the ancestral environment. The ana...

This paper studies the incidence of civil war over time. We put forward a canonical model of civil war, which relates the incidence of conflict to circumstances, institutions and features of the underlying economy and polity. We use this model to derive testable predictions and to interpret the cross-sectional and times-series variations variations in civil conflict. Our most novel emprical fin...

We use different variations of the canonical bargaining model of civil war to illustrate why a potential alliance with a third (foreign) party that affects the probability of winning the conflict can trigger or prolong an already existing civil war. We explore both political and economic incentives for a third party to intervene. The explicit consideration of political incentives leads to two p...
