Involuntary parks: Human conflict is creating unintended refuges for wildlife
Few locations on Earth are as haunting or deeply ironic as so-called involuntary parks — places too toxic, dangerous, or otherwise made off-limits for human habitation, but which have paradoxically and unintentionally become sanctuaries for wildlife in our absence. As the name coined by science fiction author Bruce Sterling suggests, involuntary parks weren’t established for […]

Tornado no Algarve parece ter “aparecido do nada”, mas o perigo estava identificado: em Portugal há um problema de “perceção do risco”
O tornado de Albufeira voltou a revelar falhas estruturais na prevenção e na preparação do país para fenómenos extremos: em vez de "rajadas fortes" é diferente dizer "estruturas ligeiras podem ser arrancadas do sítio", exemplifica um geógrafo ouvido pelo Expresso

The Kremlin has heaped praise on Donald Trump’s latest national security strategy,
calling it an encouraging change of policy
that largely aligns with Russian thinking.
The remarks follow the publication of a White House document on Friday
💥that criticises the EU and says Europeis at risk of “civilisational erasure”,

Abstract: This paper studies the fundamental properties of the high-order forward-backward splitting mapping (HiFBS) and its associated forward-backward envelope (HiFBE) through the lens of high-order regularization for nonconvex composite functions. Specifically, we (i) establish the boundedness and uniform boundedness of HiFBS, along with the H\"older and Lipschitz continuity of HiFBE; (ii) derive an explicit form for the subdifferentials of HiFBE; and (iii) investigate necessary and sufficient conditions for the differentiability and weak smoothness of HiFBE under suitable assumptions. By leveraging the prox-regularity of $g$ and the concept of $p$-calmness, we further demonstrate the local single-valuedness and continuity of HiFBS, which in turn guarantee the differentiability of HiFBE in neighborhoods of calm points. This paves the way for the development of gradient-based algorithms tailored to nonconvex composite optimization problems.

Beyond Revenue and Welfare: Counterfactual Analysis of Spectrum Auctions with Application to Canada's 3800MHz Allocation

Abstract: Spectrum auctions are the primary mechanism through which governments allocate scarce radio frequencies, with outcomes that shape competition, coverage, and innovation in telecommunications markets. While traditional models of spectrum auctions often rely on strong equilibrium assumptions, we take a more parsimonious approach by modeling bidders as myopic and straightforward: in each round, firms simply demand the bundle that maximizes their utility given current prices. Despite its simplicity, this model proves effective in predicting the outcomes of Canada's 2023 auction of 3800 MHz spectrum licenses. Using detailed round-by-round bidding data, we estimate bidders' valuations through a linear programming framework and validate that our model reproduces key features of the observed allocation and price evolution. We then use these estimated valuations to simulate a counterfactual auction under an alternative mechanism that incentivizes deployment in rural and remote regions, aligning with one of the key objectives set out in the Canadian Telecommunications Act. The results show that the proposed mechanism substantially improves population coverage in underserved areas. These findings demonstrate that a behavioral model with minimal assumptions is sufficient to generate reliable counterfactual predictions, making it a practical tool for policymakers to evaluate how alternative auction designs may influence future outcomes. In particular, our study demonstrates a method for counterfactual mechanism design, providing a framework to evaluate how alternative auction rules could advance policy goals such as equitable deployment across Canada.
