| Abstract: | Since the Seoul Declaration, access to broadband networks and the Internet have constantly increased. In terms of fixed broadband, penetration levels are close to maturity. In addition, further deployments of fibre networks have taken place; however, overall deployment of fibre is still at an early stage. On the mobile broadband side, 3G coverage is high and data traffic is expected to grow significantly. In terms of policies, national broadband plans have contributed to increasing access to the Internet. Some countries have furthermore invested public funds in the deployment of fibre networks. |

| Abstract: | Newspapers have been experiencing declining circulation figures and diminishing advertising revenues for several years – both effects might pose a threat to the continuing existence of (print) newspapers. In an earlier paper, Lindstädt & Budzinski (2011) argued from a theoretical viewpoint that industry-specific patterns exist that determine substitution or complementation effects between internet and newspaper advertising. It was argued that retail advertising, in particular, may offer a niche for regional/local newspapers that can be expected to present a sustainable segment of complementarity along with the otherwise mostly substitutional advertising markets. This paper empirically tests these hypotheses by analyzing advertising spending data for newspaper and internet display advertising of 13 different industries in the U.S. from 2001-2010. We find evidence for some of the hypotheses. Whereas some industries showed clear substitution effects between internet display and newspaper advertising, the majority of our hypotheses could be only partly rejected: newspaper substi-tution effects could be observed, however, in the direction to traditional media platforms instead of internet display advertising. For two retail-sub-industries, the hypotheses could not be rejected for the analyzed period. The authors would like to thank the College of Communications at the Pennsylvania State University and in particular Anne Hoag and Dennis Davis for hosting Nadine Lindstädt as a Research Visiting Scholar in 2010/2011 which made it possible to access and use the Kantar Media Intelligence Ad$pender™ database for this research. |

| Abstract: | The best tools to manage the exchange of information and services between heterogeneous subjects through new technological tools with particular reference to information systems are certainly the Web-based information systems. Leveraging the infrastructure of the Web, these systems may be able to handle multimedia data, to perform distributed and cooperative applications based on service, in addition to customizing applications and related data. This paper provides an overview on Web Information Systems with particular reference to GIS, presenting a description of the usage scenarios and a comparison between two significant platform for publishing spatial data. |

| Abstract: | The paper investigates R&D and ICT investment at firm level, assessing their relative importance and the extent to which they are complements or substitutes. We use data on a large unbalanced panel sample from four consecutive waves of a survey of Italian manufacturing firms, together with a version of the model developed by Crepon et al., 1998, modified to include ICT investment and R&D as the two main inputs of innovation and productivity. We find that R&D and ICT are both strongly associated with innovation and productivity, with R&D being more important for innovation and ICT for productivity. We explore their possible complementarity in innovation and production but find none, although there is complementarity between R&D and worker skill in innovation. |
