The value relevance of announcements of transformational information technology investments." Mis Quarterly (2003): 637-656. Abstract In this paper, we examine the influence of IT strategic role to extend the findings of Im et al. Specifically, we demonstrate that IT strategic role can explain how IT investments in each of the IT strategic roles might affect the firm's competitive position and ...

The main objective of this paper is to present and evaluate a method that helps to calibrate the parameters of an evolutionary algorithm in a systematic and semi-automated manner. The method for Relevance Estimation and Value Calibration of EA parameters (REVAC) is empirically evaluated in two different ways. First, we use abstract test cases reflecting the typical properties of EA parameter sp...

Our findings show that these firms use FCDs to hedge and not to speculate but that the impact of hedging strategies’ disclosures is statistically and economically weak revealing that either (i) managers hedge only a small proportion of the currency risk they are facing, or that (ii) investors make systema...

We present sufficient conditions for the existence of solutions of second-order two-point boundary value and fractional order functional differential equation problems in a space where self distance is not necessarily zero. For this, first we introduce a Ciric type generalized F-contraction and F- Suzuki contraction in a metric-like space and give relevance to fixed point results. To illustrate...
