Since the establishment of Israel sex differentials in the life expectancy at birth exhibited by Israeli Jews have been very low in comparison to other countries. This paper investigates the age and sex structure of sex differentials in mortality among Israeli Jews comparing them to the populations of Western and Eastern European countries. It also explores the similarities and differences betw...

The detour and spanning ratio of a graph embedded in measure how well approximates Euclidean space and the complete Euclidean graph, respectively. In this paper we describe time algorithms for computing the detour and spanning ratio of a planar polygonal path. By generalizing these algorithms, we obtain -time algorithms for computing the detour or spanning ratio of planar trees and cycles. Fina...

This paper considers the matching problem with regional quotas, in particular, regional minimum quotas. Although such quotas are relevant in many real-world settings, there is a lack of strategy-proof mechanisms that consider regional minimum quotas. We first show that without any restrictions on the region structure, finding a feasible matching that satisfies all quotas is NP-complete. Then, a...

the end of cold war created a unique opportunity for both the arabs and israelis to end their animosity and for the united states to play an important role to bring them to peace negotiations. therefore, during the 1990s, the u.s. facilitated several rounds of talks between syria and israel, but the negotiations complicated gradually. the talks were stalled over the fact that israel did not wan...

In 2011, more than 75,000 people died in road crashes in the ten member countries of the Association of South East Asian Nations (ASEAN) and many times this number sustained long term injuries. Improving road safety outcomes in ASEAN is not only important for the welfare and economic benefit of these countries, but given that a significant proportion of the world’s population lives in ASEAN, it...
