Remarks on the Efficiency of Information Systems

By:	András Keszthelyi (Óbuda University)
Abstract:	In Hungary there exist two big and well- known scholar information systems (SIS). Both of them have become part of everyday life in the adminis - tration of higher education. These SISes have made quite a long journey dur - ing their evolution. Even so, they have some annoying disadvantages even today; e.g. they serve too few users at a time too slowly in the case of critical activities, such as during registration for courses or for examinations. There are many circumstances which can result in such poor efficiency. In this pa - per I try to investigate the role of three- level data modelling in an indirect way. I, with a colleague of mine at Budapest Tech, planned and executed a measurement which shows that (much) better performance can be reached based on a 'good' data model, even in a poorer environment.

Digital piracy : theory

By:	BELLEFLAMME, Paul (Université catholique de Louvain, CORE and Louvain School of Management, B-1348 Louvain-la-Neuve, Belgium); PEITZ, Martin (Department of Economics, University of Mannheim, D-68131 Mannheim, Germany)
Abstract:	This article reviews recent theoretical contributions on digital piracy. It starts by elaborating on the reasons for intellectual property protection, by reporting a few facts about copyright protection, and by examining reasons to become a digital pirate. Next, it provides an exploration of the consequences of digital piracy, using a base model and several extensions (with consumer sampling, network effects, and indirect appropriation). A closer look at market-structure implications of end-user piracy is then taken. After a brief review of commercial piracy, additional legal and private responses to end-user piracy are considered. Finally, a quick look at emerging new business models is taken.
