SUMMARY:Philosophy Colloquium: \"Well-Being and the Self\"
DESCRIPTION:All are invited to a Philosophy Department colloquium talk on Monday 3rd March\, 1:30 PM\, in AC04 LR307\, by Professor Antti Kauppinen. \nTitle: Well-Being and the Self \nAbstract: The best kind of life for one person may not be the best kind of life for another person – it’s not the case that everyone is directly benefited by the same things. In this paper\, I’m going to argue that for something to be a candidate for being in itself or basically good for someone\, it must be expressive of who they are. For that to be the case\, in turn\, is for the putative good to constitute\, manifest\, or orient the person’s agency or sensibility\, or those capacities whose functioning defines who they are. Crucially\, this means that fit or suitability between a subject and a welfare good does not hang on their endorsement or resonance in terms of attitudes or hedonic states\, in contrast to prevailing views. This increases the plausibility of non-subjectivist theories of well-being. \nBio: Antti Kauppinen is Professor of Practical Philosophy at the University of Helsinki. His research focuses largely on ethics and metaethics\, on topics like normativity\, meaning in life\, well-being\, and moral sentiments. He has published papers on these topics in journals like the Journal of Moral Philosophy\, Ethics\, Philosophical Studies\, Noûs\, and Philosophers' Imprint. From 2019 to 2023\, he was the PI of the Academy of Finland Research Project Responsible Beliefs: Why Ethics and Epistemology Need Each Other\, and is now the co-PI of Maria Lasonen-Aarnio's Kone Foundation project The Many Faces of Inquiry (2024-2028).

SUMMARY:CS Online Seminar
DESCRIPTION:Abstract: Secure Multiparty computation (MPC) is a fundamental primitive in cryptography that enables mutually distrusting parties to collaborate using their private data through a communication protocol\, eliminating the need for a trusted third party. Secure MPC among 𝑛 parties can achieve perfect security if up to 𝑡<𝑛/3 parties are corrupted\, and statistical security if up to 𝑡 < 𝑛/2 parties are corrupted. These guarantees hold against malicious adversaries in the standard MPC model\, where a fixed set of parties are corrupt throughout the protocol.\nOstrovsky and Yung (PODC 1991) introduced a more dynamic setting where an adversary can periodically move through the network—uncorrupting parties and corrupting new ones—emulating real-world network attacks. In the extreme case\, an adversary may be maximally mobile\, corrupting a fresh set of parties in every round of the protocol. A related challenge arises in the You Only Speak Once (YOSO) model (Gentry et al. Crypto 2021)\, where not only is the adversary mobile\, but each round is executed by a new set of parties. Previous positive results in these settings fall short of achieving full security\, either assuming probabilistic corruption\, relying on nonstandard communication models\, or providing only security-with-abort. Whether full security with perfect/statistical guarantees can be achieved remained an open question.\nIn this talk\, I will present our results addressing both challenges. We introduce a layered MPC model\, a simplified variant of fluid MPC (Choudhuri et al.\, Crypto 2021)\, which abstracts both mobile-adversary and YOSO settings. This model structures computation over a layered graph of width 𝑛\, where parties communicate privately and broadcast messages to the next layer. We achieve perfect/statistical security with optimal corruption thresholds: 𝑡<𝑛/3 for perfect security and 𝑡<𝑛/2 for statistical security.\nThis talk is based on joint works with Bernardo David\, Yuval Ishai\, Anders Konring\, Eyal Kushilevitz (Crypto 2023)\, and with Anders Konring\, Chen-Da Liu-Zhang\, Giovanni Deligios (TCC 2024). \nAbout the Speaker: Varun Narayanan is a postdoctoral researcher in the Computer Science department at UCLA\, hosted by Prof. Rafail Ostrovsky. He previously held a postdoctoral position at Technion\, working with Prof. Yuval Ishai and Prof. Eyal Kushilevitz. He earned his PhD from TIFR\, Mumbai\, advised by Dr. Vinod Prabhakaran.\nVarun’s research focuses on theoretical and practical aspects of cryptography\, with an emphasis on secure multiparty computation. \nWe look forward to your active participation.

SUMMARY:Economics exchange- Prof Don Davis visit
DESCRIPTION:Dear All\, \nThe Isaac Centre for Public Policy and Department of Economics invites you to a public lecture by Professor Donald R. Davis\, (Ragnar Nurkse Professor of Economics and International Affairs\, Columbia University) on 3rd March 2025\, at 4:40 pm\, as part of its Eminent Speaker Series. \nFor Registration\, please fill the form HERE \nTitle: Work from Home\, Work from Anywhere: Urban and Global Economic Development \nTime: 4:40 – 5.50 PM \nVenue: AC-02- 108 \nAbstract: \nInternational trade and urbanization have been two important engines of economic growth for countries around the globe. However\, in recent years\, both have encountered significant disruptions. The COVID-19 pandemic accelerated the shift to remote work\, prompting demographic shifts as people relocated away from urban centers\, raising questions about the future of cities and labor markets. At the same time\, post-pandemic industrial policies—ranging from subsidies to tariffs—have placed new pressures on global trade dynamics\, reshaping supply chains and economic relationships between nations. As cities have historically thrived as hubs of commerce and international exchange\, these shifts in trade policies and workforce distribution are redefining the economic role of urban centers. Against this evolving landscape\, this talk will explore pressing issues and emerging ideas in urban and labor economics\, as well as international trade\, offering insights into how these forces continue to shape economic development. \nAbout the Speaker: \nProf Donald R. Davis is the Ragnar Nurkse Professor of Economics and International Affairs at Columbia University. He earned his undergraduate degree in social and ethical philosophy from the University of California\, Berkeley\, and his PhD in Economics from Columbia. Before joining Columbia\, he was a faculty member at Harvard University from 1992 to 1999. \nProf Davis has served as Chairman of Columbia’s Department of Economics and has been on various editorial boards. He is also a past president of the Urban Economics Association. His research spans multiple areas within spatial economics\, including international trade\, economic geography\, regional economics\, and urban economics. His work has explored trade theory testing\, the role of market scale in international trade\, trade and inequality\, the distribution of skills across cities of different sizes\, and the segregation of consumption by race and ethnicity within cities. \n  \n  \nBest Regards\, \nAbhishek \n
