Beyond the Cold War: New Directions for Labor Internationalism

[Excerpt] Achieving real solidarity across national borders and around the globe is a difficult undertaking, one which little in our experience has prepared us for. Language barriers, differences in cultures and political traditions, very different styles of unionism — all these make simple communication, let alone real understanding of foreign workers\u27 interests and concerns, difficult. Unfortunately, the AFL-CIO\u27s official agency for helping us sort through these difficulties — the Department of International Affairs (DIA) — is not much help in doing so. In fact, as I argue here, the DIA is often an obstacle to building real solidarity. After making this case, I will make some suggestions for how U.S. unions can move toward solidarity by avoiding the DIA structure — through direct participation in the International Trade Secretariats (ITSs), like the Metalworkers Federation mentioned above, and through forming sister union relationships with relevant unionists in other countries. But, eventually, the DIA must be opened up to reflect the broad and diverse interests of labor\u27s rank-and-file rather than the narrow sectarian face it has shown the world for the past several decades

Lattice Properties of Oriented Exchange Graphs and Torsion Classes

The exchange graph of a 2-acyclic quiver is the graph of mutation-equivalent quivers whose edges correspond to mutations. When the quiver admits a nondegenerate Jacobi-finite potential, the exchange graph admits a natural acyclic orientation called the oriented exchange graph, as shown by Br\"ustle and Yang. The oriented exchange graph is isomorphic to the Hasse diagram of the poset of functorially finite torsion classes of a certain finite dimensional algebra. We prove that lattices of torsion classes are semidistributive lattices, and we use this result to conclude that oriented exchange graphs with finitely many elements are semidistributive lattices. Furthermore, if the quiver is mutation-equivalent to a type A Dynkin quiver or is an oriented cycle, then the oriented exchange graph is a lattice quotient of a lattice of biclosed subcategories of modules over the cluster-tilted algebra, generalizing Reading's Cambrian lattices in type A. We also apply our results to address a conjecture of Br\"ustle, Dupont, and P\'erotin on the lengths of maximal green sequences.Comment: Changes to abstract and introduction; in v3, minor changes throughout, added Lemma 7.3; in v4, abstract slightly changed, final version; in v5, Lemma 7.3 from v4 removed because of an error in its proof. We give a new proof of Lemma 7.4, which cited Lemma 7.
