Sharing the Burden: How Corporatism Shapes the Division of Environmental Tax Revenue
Regulation &Governance, EarlyView.ABSTRACT This comparative study spanning more than two decades examines how corporatist institutions shape the distribution of environmental tax revenue between producers and consumers. Environmental taxes have become a key policy instrument for addressing climate change and other environmental problems, but their effectiveness and political viability ...

Holistic or Specific? Children's Inferences About Fairness and Competence Within and Across Domains
Social Development, Volume 35, Issue 4, November 2026.ABSTRACT How do children represent an individual's traits when choosing partners for a collaborative task? We examined whether 5‐ to 9‐year‐olds (N = 89) generalize fairness and competence within and across the domains of problem‐solving ability and fairness, and how these inferences shape collaborative decisions.

Signed Projective Cubes, a Homomorphism Point of View
Journal of Graph Theory, Volume 113, Issue 1, Page 38-56, September 2026.ABSTRACT The (signed) projective cubes, as a special class of graphs closely related to the hypercubes, are on the crossroad of geometry, algebra, discrete mathematics and linear algebra. Defined as Cayley graphs on binary groups, they represent basic linear dependencies.

Generalized ramsey theory for graphs, x: double stars
Discrete Mathematics, 1979 AbstractThe double star S(n, m), where n ⩾ m ⩾ 0, is the graph consisting of the union of two stars K1,n and K1,m together with a line joining their centers. Its ramsey number r(S(n, m)) is the least number p such that there is a monochromatic copy of S(n, m) in any 2-coloring of the edges of Kp.

On Tight Tree‐Complete Hypergraph Ramsey Numbers
Journal of Graph Theory, Volume 113, Issue 1, Page 88-96, September 2026.ABSTRACT Chvátal showed that for any tree T with k edges, the Ramsey number R ( T , n ) = k ( n − 1 ) + 1. For r = 3 or 4, we show that, if T is an r‐uniform nontrivial tight tree, then the hypergraph Ramsey number R ( T , n ) = Θ ( n r − 1 ). The 3‐uniform result comes from observing a construction of Cooper and Mubayi.

Extremal theory and bipartite graph-tree Ramsey numbers
Discrete Mathematics, 1988 The authors contribute to the extremal Ramsey theory on graphs. In particular Ramsey numbers for trees and bipartite graphs are upperbounded. Tecnical mechanism developed for proving the main result is interesting in its own right and seems to be useful for further researches.

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.
