Outsourcing has become one of the strategies adopted by businesses to manage their IS. During the last few years, the use of outsourcing has resulted in an increase in the volume of literature devoted to it. We decided therefore to analyse the literature with the aim of identifying the main topics, the methodologies most often applied and the authors and(More)
OBJECTIVE The present study was undertaken to investigate the effect of dietary magnesium (Mg) deficiency on plasma levels of parathyroid hormone (PTH) and calcitonin (CT), and the changes in tissue calcium (Ca) and phosphorus (P) content. METHODS Wistar rats were fed an Mg-deficient diet. Plasma levels of PTH and CT, and Ca and P content in plasma, whole(More)
The study of Information Systems (IS) is a relatively new research area, thus an analysis of the latest literature could be useful to show what the researchers are doing and what can be done to improve our approach. With that purpose in mind, this article analyzes the articles published in the Management Information Systems Quarterly and Information &(More)
Despite the considerable growth of Information Systems (IS) outsourcing in recent years, this trend is still the object of strong criticism. This study has as its aim to show the main risks computer outsourcing entails for the largest Spanish firms. In order to achieve that aim, we have reviewed the previous literature on this topic and later analysed the(More)
We performed weekly analyses of the evolution of the bioavailability of the Mg cation over a period of 70 days in adult rats fed an Mg-deficient (0.02%) diet. The results generally showed an increase in digestive utilization (% absorption) and a decrease in Mg balance during the experimental period. The parameters most sensitive to Mg deficiency were(More)
Recovery from Mg deficiency was studied in adult Wistar rats fed a semisynthetic diet containing 0.04% Mg in the form of magnesium carbonate. Daily administration of a diet containing recommended levels of calcium carbonate to Mg-deficient rats led to the recovery, within the first seven days of treatment, of normal values in most of the parameters studied:(More)
The unstoppable tendency toward Information Systems Outsourcing contrasts with the lack of success in many of these contracts, which makes it necessary to study the factors determining that success. The present paper proposes a set of key factors to achieve IS outsourcing success and also; it establishes a number of measures to value the degree of success(More)
The effect of intracerebroventricular or intraperitoneal administration of cannabinoid receptor agonist WIN 55,212-2 or inverse agonist AM 251 on food intake and extracellular levels of serotonin and acetic acid 5-hydroxy-indol from presatiated rats was studied. Compared to the vehicle-injected control, the intracerebroventricular administration of WIN(More)
