Let L be a bounded lattice, let [a, b] and [c, d] be intervals of L, and let φ : [a, b] → [c, d] be an isomorphism between these two intervals. Let us consider the algebra L↔ φ = 〈L;∧,∨, φ, φ−1〉, which is a lattice with two partial unary operations. We construct a bounded lattice K (in fact, a convex extension of L) such that the congruence lattice of L↔ φ is isomorphic to the congruence lattic...

Purpose – The purpose of this paper is to describe why trust congruence is important to negotiation, illustrate potential types of trust congruence in negotiating dyads, and link those types of congruence to joint-behavioral outcomes. Design/methodology/approach – Studies pertinent to negotiators’ trust in one another are reviewed, and based on prior theoretical and empirical work, propositions...

We define Euclidean scissor congruence groups for an arbitrary algebraically closed field F and formulate a conjecture describing them. Using the Euclidean and NonEuclidean F–scissor congruence groups we construct a category which is conjecturally equivalent to a subcategory of the category MT (Fε) of mixed Tate motives over the dual numbers Fε := F [ε]/ε . 1. Euclidean scissor congruence group...

Let L be a lattice and let L1, L2 be sublattices of L. Let be a congruence relation of L1. We extend to L by taking the smallest congruence of L containing . Then we restrict to L2, obtaining the congruence L2 of L2. Thus we have de ned a map ConL1 ! ConL2. Obviously, this is an isotone 0-preservingmap of the nite distributive lattice ConL1 into the nite distributive lattice ConL2. The main res...

For e-business, location is irrelevant and competition is intense. To succeed in this environment, organizations must find new ways to differentiate themselves from their competition. One way to achieve e-business differentiation is to foster trust by building a perception of value congruence and avoiding a perception of value conflict. We explore how value congruence contributes to and how val...

Proposition algebra is based on Hoare’s conditional connective, which is a ternary connective comparable to if-then-else and used in the setting of propositional logic. Conditional statements are provided with a simple semantics that is based on evaluation trees and that characterizes so-called free valuation congruence: two conditional statements are free valuation congruent if, and only if, t...

During the last decade, CCS has been extended in diier-ent directions, among them priority and real time. One of the most satisfactory results for CCS is Milner's complete proof system for observational congruence 28]. Observational congruence is fair in the sense that it is possible to escape divergence, reeected by an axiom recX:(:X + P) = recX:::P. In this paper we discuss observational cong...

Objective: The overall purpose of this study was to propose and test a conceptual model and apply family analyses methods to understand quality of life family congruence in the nursing home setting. Method: Secondary data for this study were from a larger study, titled Measurement, Indicators and Improvement of the Quality of Life (QOL) in Nursing Homes. Research literature, family systems theo...

Despite the importance of matching different viewpoints on IS service quality in organizations, there is still little understanding about how perceptual congruence between IS professionals and users affects user satisfaction. Drawing on cognitive dissonance theory and perceptual congruence research, our study examines 169 matched-pair survey responses using polynomial regression and response su...

Evidence of assortative mating according to personality was reported in a previous SOEP-based study (Rammstedt & Schupp, 2008). Based on population representative data of almost 7000 couples, high levels of congruence between spouses were found, which increased with marriage duration. Almost 5000 of these couples were tracked over a five-year period with personality assessed at the beginning an...
