It is shown that under mild conditions the path-component of the identity in the dual group G* of an Abelian topological group G is precisely the union of the one-parameter subgroups of CT. This yields several corollaries, including a necessary condition for certain groups to be reflexive (to satisfy the Pontrjagin duality theorem), and a negative answer to a question of N. Noble. The main resu...

This paper presents a systemic-constructivist approach to working therapeutically with couples. Therapeutic change is optimal when both the intrapersonal processes of each individual and their unique interpersonal system are synthesized. This approach targets partners’ ways of knowing and experiencing themselves in the context of their relationship. The therapist endeavors to engage the aspect ...

The affordances introduced by digital technologies are reshaping consumption practices. Individuals are now engaging in networks rather than markets, and ownership-based consumption is giving way to the previously unattractive access-based, collaborative consumption. Such consumption practices produce different relationships between objects and personal identity, on which there is limited resea...

Has Knowledge Management (KM) an identity and a future? The process of differentiating KM both as a business practice and a discipline is in a reflexive situation: it is happening amidst a major transformation of established criteria for the social recognition of a knowledge field. Awareness of this fact by stakeholders in the systematic and sustainable evolution of KM may lead to a conscious m...

Based on a property of tolerance relations, it was proved in [3] that for an arbitrary lattice identity implying modularity (or at least congruence modularity) there exists a Mal’tsev condition such that the identity holds in congruence lattices of algebras of a variety if and only if the variety satisfies the corresponding Mal’tsev condition. However, the Mal’tsev condition constructed in [3] ...

Reynolds’ theory of parametric polymorphism captures the invariance of polymorphically typed programs under change of data representation. Semantically, reflexive graph categories and fibrations are both known to give a categorical understanding of parametric polymorphism. This paper contributes further to this categorical perspective by showing the relevance of bifibrations. We develop a bifib...
