A Closed Form for the Stirling Polynomials in Terms of the Stirling Numbers
Tbilisi Mathematical Journal, 2017 In the paper, by virtue of the Faá di Bruno formula and two identities for the Bell polynomial of the second kind, the authors find a closed form for the Stirling polynomials in terms of the Stirling numbers of the first and second kinds.

ON GENERALIZATIONS OF STIRLING NUMBERS AND SOME WELL-KNOWN MATRICES [PDF]
, 2023 We introduce a generalization of the Stirling numbers of the first kind and the second kind. By arranging these numbers into matrices, we generalize the Stirling matrices of the first kind and the second kind investigated by Cheon and Kim [Stirling ...

British Educational Research Journal, EarlyView.Abstract Agency has increasingly become a central concept in educational leadership research, yet its application to those preparing to enter school leadership roles remains underexplored. Drawing on the conceptual framework of the ecological approach to teacher agency, we explored how and in what ways aspiring school leaders in Scotland (n = 21 ...

Congruences for Stirling numbers and Eulerian numbers [PDF]
Acta Arithmetica, 2008 In this paper, we establish some Fleck-Weisman type and Davis-Sun type congruences for the Stirling numbers and the Eulerian numbers.

British Educational Research Journal, EarlyView.Abstract The intertwined crises of climate change, biodiversity loss and environmental degradation represent profound global challenges. Education holds a unique role in enabling all young people to navigate uncertainty, participate meaningfully in decision‐making and contribute to more just and sustainable ways of living.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

The Group of Generalized Stirling Numbers
Advances in Applied Mathematics, 2001 An algebraic approach to the generalized Stirling numbers is presented, leading to a unified interpretation for important combinatorial functions such as the binomials, Stirling numbers, and Gaussian polynomials. Let \(G\) be the group of all infinite lower triangular matrices \(A\) over a field \(K\) of characteristic \(0\) for which \(A(n,m)= 1 ...

Business Strategy and the Environment, EarlyView.ABSTRACT We are interested in investigating whether firms use political donations as a license to neglect environmental sustainability. We further deepen the examination by exploring the role of executive contracting. Drawing on a wide range of data between 2002 and 2021 and a global sample, our findings confirm that firms use political contributions ...
