The authors used an event-contingent daily recording strategy, the Rochester Interaction Record (RIR), to examine the motivational dynamics of interpersonal relations. Using hierarchical linear modeling, the authors demonstrated that social interactions were more pleasant when participants felt autonomous, competent, and related. Autonomy, competence, and relatedness consistently predicted inte...

Recent rhetoric surrounding the contemporary aid relationship between donors and African states is couched in terms of a high level consensus between western and African political leaderships, a central pillar of which is adherence to liberal principles of governance and economic management.

This paper is a contribution to the theory of what might be termed $0$-dimensional non-commutative spaces. We prove that associated with each inverse semigroup $S$ Boolean presented by abstract versions Cuntz-Krieger relations. call this Exel completion and show it arises from Exel's tight groupoid under Stone duality.

In this paper, the concept of interval-valued intuitionistic fuzzy set to UP subalgebras and UP -ideals of UP -algebras are introduced. Relations among IVIF UP subalgebras with IVIF UP -ideals of UP -algebras are investigated. The homomorphic image and inverse image of IVIF UP -subalgebras and IVIF UP -ideals are studied and some related properties are investigated. Equivalence relations on IVI...
