Business Strategy and the Environment, EarlyView.ABSTRACT Cooperatives as a democratic form of economic organization are an emerging focus in research on the social dimensions of circular economy. However, there is no international database on cooperatives and circular economy, impeding systematic analysis.

Lagrange inversion and Stirling number convolutions [PDF]
, 2014 Recently Agoh and Dilcher proved a convolution identity involving Stirling numbers S(n, r) of the second kind. We prove an identity where S(n, r) is replaced by a more general doubly-indexed family A(n, r).

A New Symmetric Expression of Weyl Ordering
, 2004 For the creation operator $\adag $ and the annihilation operator $a$ of a harmonic oscillator, we consider Weyl ordering expression of $(\adag a)^n$ and obtain a new symmetric expression of Weyl ordering w.r.t. $\adag a \equiv N$ and $a\adag =N+1$ where $

Business Strategy and the Environment, EarlyView.ABSTRACT This research examines the potential of artificial intelligence (AI) to improve sustainability reporting, particularly in relation to environmental, social and governance (ESG) issues. Despite growing interest in the field, the integration of AI in sustainability remains underexplored, especially in terms of its impact on data accuracy ...

Bell Numbers of Complete Multipartite Graphs [PDF]
Computer Science Journal of Moldova, 2016 The {\it Stirling number} $S(G;k)$ is the number of partitions of the vertices of a graph $G$ into $k$ nonempty independent sets and the number of all partitions of $G$ is its {\it Bell number}, $B(G)$.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives
Chemistry – A European Journal, EarlyView.Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.
