Despite the huge investments by organizations in ERP implementation, maintenance, and user training, ERP implementation failures and less-than-satisfactory productivity improvements are common. End-users’ reluctance or unwillingness to adopt or use the newly implemented ERP system is often cited as one of the main reasons for ERP failures. To examine factors leading to the lack of end-user acce...

The purpose of this study is to develop a research model that integrates the relationship between innovation characteristics (innovation diffusion theory) and technology characteristics (task-technology fit model). With the research model, the current study investigates the adoption of the ‘‘personal information system,’’ a concept that we develop in the context of mobile technologies. In this ...

1. Abstract: The construction of facial composites by assembling individual facial features is common in criminal investigations. Arguably, the best known such method is E-FIT (electronic facial identication technique). However, although humans have excellent facial recognition ability, it is widely recognised that they often have great difficulty recalling facial characteristics in sufficient ...

There are reasons to believe that mechanisms exist in the solar interior which lead to random density perturbations in the resonant region of the Large Mixing Angle solution to the solar neutrino problem. We find that, in the presence of these density perturbations, the best fit point in the (sin 2θ,∆m) parameter space moves to smaller values, compared with the values obtained for the standard ...

Let X,, , X, be a sequence of independent and identically distributed random variables with an unknown underlying continuous cumulative distribution function F. Relative to this unknown distribution function suppose one would like to test a null hypothesis concerning the goodness of fit of F to some distribution function using symmetric functions of sample spacings. In some applications the nul...

It seems to be a platitude that belief is governed by a norm of truth. Isn’t the point of belief to believe truths ? Isn’t it a requirement of believing that we should not believe falsehoods? A number of philosophers, however, deny this. Although they recognise that there is an intimate connection between belief and truth, they reject the idea that this connection is normative. Indeed, they tel...

MESERVEY, R., 1971. The coastline fit of Africa and South America. Palaeogeography, Palaeoclimatol., Palaeoecol., 9: 233-243. It has become axiomatic that the pre-drift reconstruction of Africa and South America is to be made by fitting together the continental shelves. Although this procedure is very plausible, actually the detailed fit of the coastlines is better than that of the shelves and ...

We compare models of supernova (SN) neutrino emission with the Kamiokande II data on SN 1987A using Bayesian approach. These are taken from simulations and representative current 1D models. find that a brief accretion phase most favored. This result is not affected by varying overall flux normalization or considering oscillations. also check compatibility best-fit data.
