On Semi-Boolean-Like Algebras [PDF]
summary:In a previous paper, we introduced the notion of Boolean-like algebra as a generalisation of Boolean algebras to an arbitrary similarity type. In a nutshell, a double-pointed algebra $\mathbf {A}$ with constants $0,1$ is Boolean-like in case for ...

Lattices of (Generalized) Fuzzy Ideals in Double Boolean Algebras [PDF]
This paper develops the notion of fuzzy ideal and generalized fuzzy ideal on double Boolean algebra (dBa). According to Rudolf Wille, a double Boolean algebra $\underline{D}:=(D, \sqcap, \sqcup, \neg, \lrcorner, \bot, \top)$ is an algebra

Theory Propagation and Reification [PDF]
SAT Modulo Theories (SMT) is the problem of determining the satisfiability of a formula in which constraints, drawn from a given constraint theory T, are composed with logical connectives.

ABSTRACT Sustainability‐oriented collaborations are inter‐organisational arrangements where the competencies of multiple companies are pooled together to tackle environmental challenges. These collaborations differ from traditional strategic alliances in that they tackle complex goals amidst greater uncertainties that extend beyond economic performance,

Nonprofit Governance and Financial Stability: A Study of Government‐Funded Social Services
ABSTRACT Nonprofit social service providers are essential in delivering vital services, often with public funding. This study adopts a contingency perspective to explore the relationship between organizational governance and financial stability in publicly funded nonprofit organizations. We use a combination of comparative multilevel analysis (CMA) and

Algebras of Complemented Subsets
Complemented subsets were introduced by Bishop, in order to avoid complementation in terms of negation. In his two approaches to measure theory Bishop used two sets of operations on complemented subsets.
