Welcome everyone to PSJ issue 50(3)! Before we jump into this issue, we have a few announcements to make. First, we would like to announce the severing of one partnership and the beginning of another. For the past couple of years, PSJ received generous support from the University of Tennessee's Howard H. Baker Jr. Center for Public Policy. We thank the center and Dr. Matt Murray, the former director, as well as Dr. Marianne Wannamaker, the current director, for the brief but constructive relationship over the past two years. Endings are often beginnings, as is the case here. We are also pleased to announce the new partnership between the PSJ, the premier policy theory journal, and the Syracuse University Maxwell School's Center for Governance and Policy Design, one of the top policy schools in the world. We know this new partnership will continue to develop public policy scholarship in meaningful ways. Stay tuned as to how.Our second announcement is that we have some new information about PSJ's impact metrics. Clarivate is now reporting that PSJ's 2021 two-year impact factor is 4.775 which ranks PSJ #16 out of 187 Clarivate-indexed Political Science journals. PSJ also sustains a record high 2021 Scopus CiteScore of 9.2 and ranks #2 out of 160 Scopus-indexed Political Science and International Relations journals and #20 out of 1345 Sociology and Political Science journals. In short, the state of PSJ continues to be strong. That has everything to do with you: PSJ's dedicated authors, reviewers, and readership.In this issue, we have three collections of studies from three different theoretical approaches to the study of the policy process: Policy Feedback (e.g., Davis, 2021), Punctuated Equilibrium Theory (PET) (e.g., Park & Sapotichine, 2020), and the Multiple Streams Framework (MSF) (e.g., Dolan, 2021). As we would expect from PSJ, the theoretical contributions in this issue are substantial: new pathways to efficacious behavior in policy feedback (Lacombe, 2022), a provocative theory-method case by PET scholars for better understanding variance and incrementalism (Fernández-i-Marín et al., 2022), and modified hypotheses for MSF (DeLeo & Duarte, 2022), among other contributions. Substantively, in this issue, we have research covering the Affordable Care Act (ACA), firearm policy, environmental policy, energy policy, highway infrastructure, and much more! In what follows, we summarize some highlights from the collections of rigorous and theoretically sophisticated pieces that PSJ was fortunate to receive and review.
