Technological devices for social networking are produced in droves and networking through media seems to be the way of getting ahead in business. We examine what role technology plays in the creation, development and maintenance of business relationships among entrepreneurs in Copenhagen. We find that mediated communication is useful in all stages of relational maintenance but only in a support...

Relational models for diagnosis are based on a direct description of the association between disorders and manifestations. This type of model has been specially used and developed by Reggia and his co-workers in the late eighties as a basic starting point for approaching diagnosis problems. The paper proposes a new relational model which includes Reggia's model as a particular case and which al...

Recent studies on social network structures have focused on tie persistence as a distinct outcome in a tie life cycle. Tie persistence refers to continuity of a network tie across at least two consecutive time periods. We contribute to this body of knowledge by empirically comparing the influence of relational embeddedness and herding on tie persistence. We find that while both the mechanisms i...

Frequent Pattern Mining (FPM) is a very powerful paradigm which encompasses an entire class of data mining tasks. The specific tasks encompassed by FPM include the mining of increasingly complex and informative patterns, in complex structured and unstructured relational datasets, such as: Itemsets or co-occurrences [1] (transactional, unordered data), Sequences [2, 8] (temporal or positional da...

in this paper, two sets of sufficient conditions are obtained to ensure the existence and stability of a unique equilibrium point of unforced first-order fuzzy relational dynamical systems by using two different approaches which are both based on the fuzzy relational matrix of the model.in the first approach, the equilibrium point of the system is one of the centers of the related membership fu...

Presented are the theoretical and experiential foundations of the author’s interdisciplinary model of intersubjectivity, inspired by a contemporary, trans-sectarian and creative re-envisioning of the Buddhist doctrine of dependent co-arising (paticca samuppada). Relational Dharma seeks to illuminate the nature of co-genesis through engaging awareness within a progression of insight within inter...

The calculus of relational algebra has its roots in the second half of the last century with the pioneering work on binary relations of G. Boole, A. de Morgan, C.S. Peirce, and E. Schröder. The modern axiomatic development is due to A. Tarski and his co-workers. In the last two decades this formalization has been accepted by many mathematicians and computer scientists as a fruitful base for des...

In "Axiomatisation of fuzzy multivalued dependencies in a fuzzy relational data model" [1), Bhattacharjee and Mazumdar have introduced an extension of classical multivalued dependencies for fuzzy relational data models. The authors also proposed a set of sound and complete inference rules to derive more dependencies from a given set of fuzzy multivalued dependencies. We are afraid an important ...
