I'm thrilled to be joining @Cornell as the Harold Tanner Dean of @CornellCAS. Cornell’s longstanding commitment to "any student, any study" aligns perfectly with my own values and commitments. The College plays a central role in that. I feel so lucky and can't wait to start.
Peter John Loewen, director of the Munk School of Global Affairs and Public Policy at the University of Toronto, has been named the 23rd dean of the Cornell University College of Arts and Sciences (@CornellCAS). news.cornell.edu/stories/202…

I never met Gordon Wood, but I have a story about him. In one of my grad school seminars, we read Wood’s Creation of the American Republic. The sheer erudition and evidentiary depth of the book bowled me over. Back then, before kids and before life accelerated to warp speed, I used to call my mother every Sunday to catch up. Lots of times, we ended up talking about what I was reading that week in my grad seminars or for leisure. Mom had an omnivorous mind, and she was always looking for something else to read. She was a true intellectual—curious about almost everything, always eager to integrate new arguments or ideas into her existing schemas of how the world worked or to have those schemas challenged and changed. When we talked that particular Sunday, I think I tried to describe to her part of Wood’s argument about the relationship between the state constitutions during the Articles of Confederation era and the federal Constitution. Maybe I was tired, maybe I didn’t completely understand her questions, but the end result of the conversation was that Mom had questions about Wood’s argument that I didn’t answer satisfactorily. I told her that she should probably just read the book, and we said goodbye. She did eventually read the book, but the next Sunday, Mom started our conversation by saying, “Well, I had a lovely conversation with Gordon Wood this week.” For a split second, I thought she was joking, but then I remembered who I was dealing with. I started to sweat. “How?” I asked. A whole variety of unlikely scenarios in which the foremost historian of the American Revolution and my mother, who lived in Wichita, Kansas, might have met ran through my mind. “Oh, I just looked up his office phone number on Brown’s website and called, and he picked up!” Mom said. I decided I would have to find another profession. As it ended up, Gordon Wood spent about an hour on the phone with my mother answering her questions about the Constitution. Ever since, I’ve had a soft spot for the man when I imagine him picking up the phone in Providence and finding Becky Elder from Wichita on the other end of the line. His generosity in that moment spoke very well of him. Rest in peace, professor.

This is terribly sad news. I knew Raúl through @EGAPTweets, but especially through his contributions online. He built up a remarkably large community of followers by simply being himself: generous, meticulous, serious but also silly, and convinced academia mattered. A huge loss.
La FLACSO México lamenta el sensible fallecimiento del Dr. Raúl Pacheco-Vega entrañable profesor-investigador, colega, amigo y miembro muy querido de nuestra comunidad académica. Expresamos nuestras más sentidas condolencias a sus familiares, amistades, colegas, estudiantado y a las comunidades académicas de las que formó parte.

He was really a tour de force, with great passions and obsessions: the craft and act of writing, the aesthetics of hotels, the merits of various highlighters, and water. But most of all he was generous towards others. My deepest condolences to his family and friends. Vale, Raúl.

Today is @MountAllison Homecoming, featuring Eric Lapointe, the greatest Canadian college player of all time. Here is his great induction speech into the Canadian Football Hall of Fame. It makes me proud to be a Canadian and an Allisonian. youtube.com/watch?v=7JZG9N2T…

I'd start by pointing out that The Game, for better or worse, is basically unchallenged as the best nonfiction book about pro hockey. There's no true equivalent in football or basketball; for baseball 50 people would give 30 different answers.
I had a conversation with a colleague today at Cornell about Ken Dryden. He's a legend here. Arguably the greatest Big Red athlete of all time. But it seemed otherwise impossible for me to describe to an American what Ken Dryden's standing was in Canada.

We mourn the loss of Ken Dryden ’69, a Cornell hockey legend and NHL icon, who passed away at 78. His 76 wins, 1967 NCAA title, and six Stanley Cups with Montreal inspired us all. Ken’s brilliance as a student-athlete and leader will always be remembered. news.cornell.edu/stories/202…

And more still, he had success in business, in the business of hockey, and then in politics. He dignified every arena he went into, and was never degraded by the dark side of any of those careers.

Maybe that's what also made him a great Cornelian. He was tough and he was kind. I feel awfully proud that he was a graduate of the College, that his number hangs in Lynah, and that he spoke glowingly of his time on the hill. What a huge loss for so many. Vale, Ken Dryden.

Above it all, he embodied the best of Canadian culture and none of its shortcomings. He wanted to be the very best in all he did, but he did it humbly and quietly. He was unflappable and tough as nails. He cared deeply for others and sought to dignify them.

Let’s all remember that it is pronounced gary-mander. As though it was named after Gary Shandling, not Jerry Seinfeld.

I think this is a very good thread on how to subject nudges to fair tests.

I think the issue is the "nudge" movement has misunderstood the point of the original "libertarian paternalism" paper and the "nudge" book. Original works argued that seemingly irrelevant factors can have an impact on behavior when *a set of conditions are met*🧵
