. Several sectors within Information and Communication Technology demonstrate a shift from purely market-based selection of standards or purely negotiated selection of standards to hybrid selection processes, where both market competition and negotiation play a role. Negotiated standard setting processes (such as those organised by the ITU) assure interoperability of technical components and services. Private firms, however, increasingly tend to undercut these collective actions. Their innovations jump-start new developments, but also create incompatibilities, lock-in effects, and pockets of market power. Internet telephony is an example, where firms, standard setting alliances, and political institutions create a hybrid market-based / negotiated standard setting environment. The paper explores the development of this hybrid networking environment. It posits propositions which are illustrated by means of case studies of the DVD and Internet telephony. 1 We thank researchers at KPN Re...

The diffusion of new technologies is their adoption by different economic agents at different times. A classical concern in the diffusion of technologies (Griliches 1957) is the importance of raw technical progress versus economic forces. We examine this classical issue in a modern market, web browsers. Using a new data source, we study the diffusion of new browser versions. In a second analysis, we study the determination of browser brand shares. Both analyses let us examine the important of technical progress vs. economic forces. We find that the critical economic force was browser distribution with a complementary technology, personal computers (PCs). In both of our analyses, distribution had a larger effect on the rate and direction of technical change than technical browser improvements. This shows an important feedback. Widespread use of the Internet spurred rapid expansion of the PC market in the late 1990s. Our results show that the rapid expansion in PCs in turn served to increase the pace of diffusion of new browsers and thus move the economy toward new mass market commercial Internet use.

This dissertation analyses two different paradigms used for the development of a software product, Operating Systems. The targets of research are two groups that operate in very different ways, Microsoft Corporation and the Linux Community. Through the observation of the strategies and methodologies used by these actors in their work, and taking into account the constraints to which they are subject, assesses, from a dynamic perspective, the relative strengths and weaknesses of their competing paradigms. In the dissertation I will analyse the efficiency of the development processes that they have adopted for the design, improvement and enhancement of their products. A theoretical model based on Giovanni Dosis "Technological Paradigms" framework, incorporating institutional, industrial, social and cultural aspects, is constructed and specifically adapted to the software industry case. The private management of technology issues considered during the analysis of the development processes inside different organisations are linked to questions having to do with the evolution of high technology, networked, markets. This analysis lends to assessment of some rationales and potential strategies for public intervention in the Operating Systems industry, taking into account some relevant concerns that have been raised about competitive issues and dominant position in this market, one of strategic importance for the future development of the Information Society

papers, but a corresponding increase in the quality of each submission for conference. The authors represent a cross-section of international perspectives that include the United Kingdom, South-East Asia, the United States of America and Australia. All published papers were double blind peer-reviewed before acceptance into the conference for publication. There were a total of 13 papers submitted for review from which only 6 were accepted and presented. The 9 th Australian Information Warfare and Security Conference is one of four conferences that form the 2008 SECAU Security Congress. The congress reflects an overarching commitment to bringing together a broad spectrum of security topics under a single assembly in order to promote and develop a cross disciplinary approach to a continuum of security research. Conferences such as the 9 th Australian Information Warfare and Security Conference take a great deal of co-ordination, time and effort in order to bring together the right people in a common forum in order to advance the wider security understanding and to progress the various research directions. To that end, I express my thanks to the conference committee
