National Security Law, Lawyers, and Lawyering in the Obama Administration

Thank you for this invitation, and thank you, in particular, Professor Hathaway, for your work in the national security legal field. Since we first met last fall, I have appreciated your scholarship and our growing friendship. I was pleased to welcome you to the Pentagon in December to introduce you to a number of my civilian and military colleagues there. I would like to count on you as someone with whom I can consult from time to time on the very difficult legal issues we wrestle with in national security

The Presidential Succession Act at 75 | Keynote Address

These remarks were delivered as part of the program entitled The Presidential Succession Act at 75: Praise It or Bury It?, which was held on April 6, 2022, and hosted by the Fordham University School of Law. The Presidential Succession Act sets out the presidential line of succession and other procedures for situations in which the president and vice president have both died, resigned, been removed, or become unable to discharge the presidency’s powers and duties. The Act also addresses succession scenarios before Inauguration Day. In light of the statute’s seventy-fifth anniversary, this program explored relevant history and analyzed whether reform to the statute is needed. In these remarks, former Homeland Security Secretary Jeh C. Johnson, a Partner at Paul, Weiss, Rifkind, Wharton & Garrison LLP, draws on his experience as an official in the presidential line of succession. Secretary Johnson served as the “designated survivor” for the 2016 State of the Union Address and the 2017 Inauguration

Coevolutionary systems and PageRank

Coevolutionary systems have been used successfully in various problem domains involving situations of strategic decision-making. Central to these systems is a mechanism whereby finite populations of agents compete for reproduction and adapt in response to their interaction outcomes. In competitive settings, agents choose which solutions to implement and outcomes from their behavioral interactions express preferences between the solutions. Recently, we have introduced a framework that provides both qualitative and quantitative characterizations of competitive coevolutionary systems. Its two main features are: (1) A directed graph (digraph) representation that fully captures the underlying structure arising from pairwise preferences over solutions. (2) Coevolutionary processes are modeled as random walks on the digraph. However, one needs to obtain prior, qualitative knowledge of the underlying structures of these coevolutionary digraphs to perform quantitative characterizations on coevolutionary systems and interpret the results. Here, we study a deep connection between coevolutionary systems and PageRank to address this issue. We develop a principled approach to measure and rank the performance (importance) of solutions (vertices) in a given coevolutionary digraph. In PageRank formalism, B transfers part of its authority to A if A dominates B (there is an arc from B to A in the digraph). In this manner, PageRank authority indicates the importance of a vertex. PageRank authorities with suitable normalization have a natural interpretation of long-term visitation probabilities over the digraph by the coevolutionary random walk. We derive closed-form expressions to calculate PageRank authorities for any coevolutionary digraph. We can precisely quantify changes to the authorities due to modifications in restart probability for any coevolutionary system. Our empirical studies demonstrate how PageRank authorities characterize coevolutionary digraphs with different underlying structures
