Previous research has demonstrated that the production of information services can be characterized at the aggregate economy-wide level by the Cobb-Douglas production function. However, the underlying production process at the firm level has not yet been ascertained. The objective of this paper is to determine the form of the production process for information systems services at the firm level...

In this paper we extend the study done by Ferrara and Guerrini [12], where two different research lines within the Ramsey model were joined together: the one studying the role of a logistic population growth rate (Accinelli and Brida [2]), and the one analyzing the effects of a Benthamite formulation for the utility function. The results obtained in [12] for the special case of a constant inter...

Background Brace treatment for scoliosis is effective. The short term in-brace correction of the Cobb angle is associated with end results and success of bracing. Irrespective of the factors which determine the correction the measurement of the Cobb angle is a possibility to evaluate the brace quality. We have investigated the braces from one orthotist over a fixed period of time and have descr...
