The goal of Multi-Party Computation (MPC) is to perform an arbitrary computation in a distributed, private, and fault-tolerant way. For this purpose, a fixed set of n parties runs a protocol that tolerates an adversary corrupting a subset of the participating parties, and still preserves certain security guarantees. Most MPC protocols provide security guarantees in an all-or-nothing fashion: Ei...

1. Common and shared responsibility is a principle of international law and is applied in many fields of cooperation. It is thus not specific to drug control. Whereas international treaties establish a set of rules creating individual obligations for States parties, the principle of common and shared responsibility goes much further. It provides the framework for a cooperative partnership among...

In synchronous networks, protocols can achieve security guarantees that are not possible in an asynchronous world: i.e., they can simultaneously achieve input completeness (all honest parties’ inputs are included in the computation) and guaranteed termination (honest parties do not “hang” indefinitely). In practice truly synchronous networks rarely exist, but synchrony can be emulated if channe...

Background: During recent years, scientists have presented several methods for treating infertility; these methods occasionally are highly efficient for infertile couples but can be concerning because of legal and ethical issues. One of these methods is surrogacy. Surrogacy is used when the main etiology of infertility is in the uterus caused by these three reasons: lack of uterine‚ congenital ...

Two studies shed light on construals (i.e., attributions of responsibility and perceived severity of harm) of extreme intergroup violence and the relationship between in-group identification and these construals. An investigation of Turkish construals of Armenian massacres at the beginning of the 20th century (Study 1) and Hutus’ and Tutsis’ construals of the ethnic conflict in Burundi (Study 2...
