Using K-Causal relation introduced by Sorkin and Woolgar , we generalize results of Garcia-Parrado and Senovilla 7 on causal maps. We also introduce new concepts like K-future sets,K-reflecting and K-future distinguishing space-times, and prove some of their properties.This approach is simpler and more general as compared to traditional causal approach 2,3 and it has been used by Penrose et.al ...

the objective of the current study is to identify the role of professional development components in developing organizational entrepreneurship in agricultural extension management of kermanshah province. the study was fulfilled by using correlation method and relational-causal model. all the agricultural extension agents in kermanshah province equal to 456 people formed the population of this ...

Two-dimensional coupled map lattices have global stability properties that depend on the coupling between individual maps and their neighborhood. The action of the neighborhood on individual maps can be implemented in terms of “causal” coupling (to spatially distant past states) or “non-causal” coupling (to spatially distant simultaneous states). In this contribution we show that globally stabl...

Decision-making typically requires judgments about causal relations: we need to know the causal e§ects of our actions and the causal relevance of various environmental factors. We investigate how several individualsí causal judgments can be aggregated into collective causal judgments. First, we consider the aggregation of causal judgments via the aggregation of probabilistic judgments, and iden...

Remote sensing has changed modern oceanography by proving synoptic periodic data which can be processed. Since the satellite data are usually too much and nonlinear, in most cases, it is difficult to distinguish the patterns from these images. In fact, SOM (Self-Organizing Maps) model is a type of ANN (Artificial Neural Network) that has the ability to distinguish the efficient patterns from th...

To efficiently support collaborative semantic management of digital resources, this paper introduces MetaSemflow, a vertical semantic flow of metadata integration to capitalize on the diversity of available metadata sets. In this paper, we aim at applying our approach on digital resources shared between agricultural communities. MetaSemflow proposes a metadata inheritance integration by combini...

Fluctuations of the mean field of a globally coupled dynamical systems are discussed. The origin of hidden coherence is related with the instability of the fixed point solution of the self-consistent Perron-Frobenius equation. Collective dynamics in globally coupled tent maps are re-examined, both with the help of direct simulation and the Perron-Frobenius equation. Collective chaos in a single...
