Strategic Change, EarlyView.ABSTRACT The increasing prevalence of corporate scandals and dysfunction linked to psychopathic leaders has prompted significant research into the drivers and effects of psychopathy in business. This paper examines corporate psychopathy, focusing on individuals with extreme selfishness, callousness, and manipulative behavior who often achieve ...

Partitioning Steiner triple systems into complete arcs
, 1991 For a Steiner triple system of order v to have a complete s-arc one must have s(s + 1)/2⩾v with equality only if s = 1 or 2 mod 4. To partition a Steiner triplesystem of order s(s + 1)2 into complete s-arcs, one must have s = 1 mod 4.

The Embedding Problem of Any Steiner Triple Systems Into Kite-Designs
Journal of MathematicsA G-design V,B is called embedded into an H-design V∪W,C if G is a subgraph of H and there is an injective mapping f:B⟶C such that B is a subgraph of fB for every B∈B.

Sequencing partial Steiner triple systems [PDF]
Journal of Combinatorial Designs, 2019 AbstractA partial Steiner triple system of order is sequenceable if there is a sequence of length of its distinct points such that no proper segment of the sequence is a union of point‐disjoint blocks. We prove that if a partial Steiner triple system has at most three point‐disjoint blocks, then it is sequenceable.

The Nexus Between Circular Economy and Sustainable Supply Chain Management: PRISMA Methodology
Sustainable Development, EarlyView.ABSTRACT The intersection of sustainable supply chain management (SSCM) and circular economy (CE) has attracted increasing academic and practical attention, emphasizing the need for integrated sustainability approaches. This study employs the PRISMA protocol and conceptualizes the CE–SSCM relationship as a dynamic system in which internal capabilities,

Some results on quadrilaterals in Steiner triple systems
, 1992 In this paper, we study quadrilaterals in Steiner triple systems. We present two recursive constructions for Steiner triple systems having no quadrilaterals. We also consider the maximum number of quadrilaterals a Steiner triple system of any given order

On the Block Coloring of Steiner Triple Systems
Journal of Mathematical Extension, 2014 A Steiner triple system of order v, STS(v), is an ordered pair S = (V, B), where V is a set of size v and B is a collection of triples of V such that every pair of V is contained in exactly one triple of B.

Decompositions of the λ-Fold Complete Mixed Graph into Mixed 6-Stars
AppliedMathGraph and digraph decompositions are a fundamental part of design theory. Probably the best known decompositions are related to decomposing the complete graph into 3-cycles (which correspond to Steiner triple systems), and decomposing the complete ...

On Steiner and Similar Triple Systems.
MATHEMATICA SCANDINAVICA, 1969 Given a finite set \(S\), a Steiner triple system over \(S\) is a system of triples of elements of \(S\) such that each pair of distinct elements is contained in just one triple. By extending a method of Skolem the author gives a simple direct construction in all cases.

Sustainable Development, EarlyView.ABSTRACT ‘Hard’ natural sciences have extensively been used to provide evidence that climate change is happening and climate action is needed. If the contribution of our economic activities to disturbing our climate systems is now largely accepted, the way in which we design and operationalise ‘climate action’—how we transition to more sustainable ...
