The conversion of database application programs is investigated when migration is required from a system with navigation (CODASYL-like) db interface to a system with specification db interface but the database semantics is not changed. We propose an analysis technique of the source program which heavily relies on program control flow. When the program semantics in analyzed from the point of view of data usage, the db statements appearing in the program are associated with one or more semantic record access patterns. A technique is given for analyzing these multiple associations and combi- ning the access patterns into db queries. Decompilable programs are those which have reducible flow graphs.

Customer Relationship Management (CRM) turns out to be a relevant source of competitive advantage in a highly competitive scenario, as in the video game’s industry. Thereby, the main objective of this study is to develop and validate a scale to assess players’ perceptions regarding aspects they consider relevant in their relationship with Nintendo Wii games, the world’s market leader in the video game’s industry. We conducted a qualitative and quantitative study with 493 subjects using both exploratory and ordinal factor analysis to compare the results. We’ve also assessed the influence of some demographics (age, gender, and frequency of playing) on players’ perceptions concerning their relationship with video games, specifically Nintendo Wii games. The results of both factor analyzes were pretty similar and the scale showed good psychometric parameters. This research is a starting point to provide a comprehensive valid measure of CRM based on customers’ perspectives regarding video games. As practical implications, the CRM scale for video games may be used as an important diagnostic tool for Nintendo as well as for companies that develop electronic games in general. Moreover, it contributes to the deepening of studies on CRM measures for the business-to-consumer (B2C) market, still scarce on the marketing literature.

How to use computers in primary schools is often discussed among those in- volved in education. In our project we introduce robot programming in order to give both children and teachers the opportunity of concretely approaching the basics of informatics as a science while performing activities concerning the standard curricula subjects. Fundamen- tal components of our proposal are: a) the

In July 2007, in the Italian northwest region named Piedmont, a number of teachers and school headmasters created a School-Net for k-12 "Educational use of robotics". The School-Net aims at promoting Papert’s constructionism in a cooperative environment and at setting up a model of small robots programming activities integrated in standard curricula covered in k-12 school years. The project is
