This paper outlines and analyses the behaviours of small and medium enterprises with respect to the evaluation of electronic commerce investments, and the subsequent realisation of the anticipated benefits from those investments. The responses of executives who participated in the study suggested that on-going involvement in electronic commerce did not come cheaply. Nonetheless, our study sugge...

Bivariate semi-logistic and Marshall-Olkin bivariate semi-logistic distributions are introduced. Some properties of these distributions are studied. First order autoregressive processes with bivariate semi-logistic and Marshall-Olkin bivariate semi-logistic distributions as marginals are introduced and studied.

Introduction Marshall Syndrome or PFAPA is an inflammatory periodic disease characterized by periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis. Restless, headache, abdominal pain, vomiting, hepatosplenomegaly and arthralgia are less common symptoms seeing in this disease. The diagnosis is established on the basis of clinical criteria that require the presence of a recurrent...

The aim of this article is to assess Friedman’s claim, put forward in his 1949 article on the Marshallian demand curve, that there is a methodological divide between the Marshallian and Walrasian approaches. Friedman’s argument will be critically examined and compared with the views he expressed in other articles written around the same time. My evaluation will lead to a mixed conclusion. Posit...

Objective: The goal of this study were to identify the factors that may predict the outcome of subarachnoid hemorrhage (tSAH) patients, and to assist in the management of their treatment. Methods: We retrospectively studied 90 patients admitted to our hospital in the two-year period from January 1, 2003, to December 31, 2004, with an initial computed tomographic (CT) diagnosis of tSAH. Follow-u...

In this paper, a new distribution called Marshall-Olkin Exponentiated Fréchet (MOEFr) is proposed. The goal to increase the flexibility of existing by including an extra shape parameter, resulting into more flexible that can provide better fit various data sets than baseline distribution. A generator method introduced Marshall and Olkin used develop Some properties such as hazard rate function,...

This study presents an application of neural networks (NN) for the prediction of Marshall test results for polypropylene (PP) modified asphalt mixtures. PP fibers are used to modify the bituminous binder in order to improve the physical and mechanical properties of the resulting asphaltic mixture. Marshall stability and flow tests were carried out on specimens fabricated with different type of ...
