In amplifying voices authors, contend that have been confined and restrained by western hegemonic notions rationalism, reductionism, empiricism, mechanism, dualism, causality for too lon...

Activity duration is uncertain due to the variations in the real world such as weather, resource availability. Utilization of uncertain planning leads to project scheduling with more stability against environmental variations. This paper presents a new optimal model for time-cost trade-off problem in fuzzy environment. In order to solve this problem, we develop a new solution method for possibi...

The option pricing problem is one of central contents in modern finance. In this paper, European option pricing formula is formulated for fuzzy financial market and some mathematical properties of them are discussed.

Ecological data is very costly and difficult to collect, and quite often the sampled data are insufficient for further spatial analysis. Today, we as spatial modellers are often presented with the situation whereby a set of data is collected already, although from the viewpoint of spatial analysis the data is insufficient, but re-sampling is impossible because of the cost and time limits. In th...

European Journal of Information Systems (2012) 21, 469–478. doi:10.1057/ejis.2012.38 In this editorial I would like to make a general and effective call for more diversity in information systems research genres. This is a general call that goes beyond a particular journal and attempts to provide some practical guidelines. One can be sympathetic to the vision of opening up to a new wider set of ...
