Another look on tense and related operators
, 2022 Motivated by the classical work of Halmos on functional monadic Boolean algebras we derive three basic sup-semilattice constructions, among other things the so-called powersets and powerset operators.

Insect Science, EarlyView.Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Algebras of sets and combinatorics
, 2002 An algebra on a set X is a family of subsets of this set closed under the operations of union and difference of two subsets. The main topic of the book is the study of various algebras and families of algebras on an abstract set X.

Some culture is hiding in plain sight in research on child development
British Journal of Developmental Psychology, EarlyView.Abstract Child development is cultural in nature, yet a divide persists between a (cross‐)cultural developmental science niche alongside a seemingly a‐cultural mainstream. In particular, childhood research relying on convenience sampling in often Western, post‐industrial (i.e., WEIRD) societies rarely ventures into issues of culture and context ...

Social and emotional pathways to shame reduction: An RCT with preservice teachers
British Journal of Educational Psychology, EarlyView.Abstract Background Shame is an unpleasant, activating emotion that has been shown to undermine learners' motivation and achievement and identity development in mathematics education. Recent studies have implemented positive psychology interventions (PPIs) to reduce preservice teachers' shame in mathematics, with promising quantitative outcomes ...

A Representation of Relation Algebras Using Routley-Meyer Frames
, 1992 A representation of relation algebras is given by modifying the Routley-Meyer semantics for relevance logic. This semantics is similar to the Kripke semantics for intutionistic logic, but it uses a ternary accessibility relation instead of a binary one ...

An extension of the basic local independence model to multiple observed classifications
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model

Modal restriction semigroups: towards an algebra of functions
, 2011 Restriction semigroups model algebras of partial maps under composition and domain. Here we consider restriction semigroups for which the usual Boolean operations on domains are modeled.

Creativity and Innovation Management, EarlyView.ABSTRACT Creativity and innovation are often understood as the result of a complex interplay of hierarchical factors, such as national, regional and firm characteristics, or between organisational and individual factors. While recent applications of qualitative comparative analysis (QCA) have begun to model such configurational links, their ...

Is free trade good for renewable resources? Brander and Taylor redux
Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.Abstract This paper generalizes the original Brander and Taylor model of open‐access renewable resource use and trade to address three common critiques. First, I introduce heterogeneity across agents in harvesting productivity to smooth out the model's extreme specialization patterns while maintaining its Ricardian structure and tractability. Second, I
