. In these cases, the watermark detector unambiguously identifies the owner. Further, the use of Gaussian noise, ensures strong resilience to multiple-document, or collusional, attacks. Experimental results are provided to support these claims, along with an exposition of pending open problems.

where intermediate nodes in the hierarchy can derive the secret keys for each of its children without any limitations or prior knowledge on the number of such children or their identities; • Resilient: the scheme is fully resilient against compromise of any number of leaves in the hierarchy, and of a

become inactive, and such node failures can propagate through the network due to rerouting of flow. We prove some properties of these dynamical networks and study the resilience of such networks under distributed routing policies with respect to perturbations that reduce link-wise flow functions

A strong equilibrium (Aumann 1959) is a pure Nash equilibrium which is resilient to deviations by coalitions. We define the strong price of anarchy to be the ratio of the worst case strong equilibrium to the social optimum. In contrast to the traditional price of anarchy, which quantifies the loss

trace of Digg, a popular news voting site, we have found strong evidence of attack on many articles marked “popular ” by Digg. 1

ABSTRACT—Until recently, resilience among adults exposed to potentially traumatic events was thought to occur rarely and in either pathological or exceptionally healthy indi-viduals. Recent research indicates, however, that the most common reaction among adults exposed to such events is a

behaviors of their misconfigured counterparts. In this paper, we describe our development of a general theory called Strong Detection that examines routing protocols in environments where some misconfigured routers “misbehave” and (intentionally or unintentionally) issue inaccurate reports that shift

April marked the 1-year anniversary of the Boston MarathonBombings,which brought our city to a stand-still as we endured a terrorist attack, manhunt, and subsequent lockdown of the metropolitan area. Twin explosions near themarathon finish line, occurring just minutes apart, left 3 people dead and hundreds in-jured. In the hour that followed the bombing, the city of Boston and privately run ambulance crews, with the aid of first responders, bystanders, and trained volun-teers, triaged and transported 118 patients to 9 differ-ent hospitals, including the city’s 7 major trauma cen-ters, preventing what could have been a much higher death toll. In the ensuing disorder, families were sepa-rated, belongings misplaced, and hundreds of runners stopped before they could finish the race.

Abstract An ecological conceptualisation of resilience was one of the major orientating concepts for this doctoral research which used critical realist methodology to gain explanatory insight into the job retention challenges faced by employees recovering from mental health problems. Methods
