Some remarks on Von Neumann regular rings
Some remarks on Von Neumann regular ringsIn this paper, we characterize strongly regular rings via idempotents from different sides. The following conditions are shown to be equivalent for a regular ring R: (1) R is strongly regular. (2) [e,x] = 0 for all e ∈ E(R), all x ∈ N(R). (3) N(R) ⊆ C(R). (4) E(R) is closed under the multiplication in R. (5) E(R) is weakly commutative. (6) For all e,f ∈

Redistribution and labor market inclusion
The Scandinavian Journal of Economics, EarlyView.Abstract This paper incorporates labor market inactivity and long‐term unemployment into the framework of optimal redistributive taxation. We examine how a combination of education policy, public employment programs, unemployment benefits, and optimal income taxation can effectively address both redistributive goals and the persistent challenges of ...

Green Space Production as a State Project in Urban China
Transactions of the Institute of British Geographers, EarlyView.Short Abstract We examine the politics of developing Chengdu's greenway project by advancing the concept of state entrepreneurialism through strategic embeddedness and tactical mobilisation. We define strategic embeddedness as the institutional integration of market into the state apparatus to achieve the state's strategic goals and tactical ...

Zoologica Scripta, EarlyView.ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.Abstract Perennial grasses and legumes are important for the reclamation of salt‐affected land. A comparison study on salt tolerance of alfalfa (Medicago sativa L.) and hybrid wheatgrass (Elymus hoffmannii) could contribute to understanding the relative salt tolerance of these species, in addition to providing germplasm information for salt tolerant ...
