Technological agglomeration and the emergence of clusters and networks in nanotechnology

Based on the analysis of two clusters in nanotechnologies (MESA+ in the Netherlands and Minatec in Grenoble in France), the paper examines the emergence and effects of technological agglomeration. The social and technical arrangements of a regional centre for nanotechnology both enable and constrain the ongoing activities and research lines that can be followed. Technology platforms and their co-location are a pre-requisite for nanotechnology research and agglomeration of such platforms are both a means and outcome for institutional entrepreneurs to mobilise resources, build networks and construct regional centres of excellence in nanotechnology. Technological agglomeration shapes the networks that evolve and leads to the convergence of scientific disciplines.TECHNOLOGICAL AGGLOMERATION;TECHNOLOGY PLATFORM;CLUSTER;DISTRICT; CONVERGING TECHNOLOGY;MULTILEVEL ACTIVITIES

A process of rumor scotching on finite populations

Rumor spreading is a ubiquitous phenomenon in social and technological networks. Traditional models consider that the rumor is propagated by pairwise interactions between spreaders and ignorants. Spreaders can become stiflers only after contacting spreaders or stiflers. Here we propose a model that considers the traditional assumptions, but stiflers are active and try to scotch the rumor to the spreaders. An analytical treatment based on the theory of convergence of density dependent Markov chains is developed to analyze how the final proportion of ignorants behaves asymptotically in a finite homogeneously mixing population. We perform Monte Carlo simulations in random graphs and scale-free networks and verify that the results obtained for homogeneously mixing populations can be approximated for random graphs, but are not suitable for scale-free networks. Furthermore, regarding the process on a heterogeneous mixing population, we obtain a set of differential equations that describes the time evolution of the probability that an individual is in each state. Our model can be applied to study systems in which informed agents try to stop the rumor propagation. In addition, our results can be considered to develop optimal information dissemination strategies and approaches to control rumor propagation.Comment: 13 pages, 11 figure

"Hello, is There Anybody Who Reads Me?" Radio Programs and Popular Facebook Posts

Radio stations are increasingly active on social networks, as radio continues to adjust and adapt to online spaces. This research is intended to conceptualize and characterize the success of radio programs beyond their native FM environment, focusing on their attempts at achieving popularity on social networks. Success on social networks is measured by user involvement and interaction with posted content and comments. This study looked at the activity of leading Israeli radio programs on Facebook pages and user engagement, evaluating highly involved posts by coding. It was found that radio program activity on social networks expands the reach of radio stations and promotes higher levels of interaction with listeners beyond broadcast schedule. In addition, integration of various media forms such as videos or images increases the likelihood of a post becoming popular. This research presents the convergence of radio programs in accordance with the theoretical framework of technological determinism

Telecomunicaciones, convergencia y regulación

This paper provides an analysis of the convergence process in the development of the telecommunication sector and evaluates its impact on market structure and policy in Telecommunication and Information Technologies (ICT), in order to identify sensitive regulatory issues and some aspects that have not yet been discussed in depth. Regulatory models have responded to the challenges raised by the market and technological development, but models that can anticipate innovations are still required. Thus, the need arises for a new generation of regulation that can generate synergies to harmonize the regulations that govern the sector’s industries, and to assess the impact of policies on social, economic and cultural rights associated with the ubiquity of networks and information.regulation and industrial policy, technological change government policy

Blockbusters for the youtube generation : a new product of convergence culture

While scholars have paid much attention to YouTube in a Web 2.0 environment, the YouTube blockbuster is yet to be discussed as part of this convergence culture. It differs from transmedia storytelling in that no single company owns or controls the characters or concepts. Once users have elevated videos with rich narrative qualities to the heights of fame within YouTube and other virtual social networks, they are taken from the YouTube archive by global commercial media and given new exchange values in traditional media forms such as books, films, television shows and ancillary products, using fragmented classical narrative techniques to do so. This paper traces the history of the blockbuster as a way of large commercial media adapting to social and technological change after World War II, to its refinements in the 1970s to cater for younger audiences and changes in the media landscape, to its most recent incarnation in YouTube. We argue that the economic and cultural values of the blockbuster are being transformed and refigured by the new form it has begun to take within convergence culture.<br /

Managing ubiquitous eco cities: the role of urban telecommunication infrastructure networks and convergence technologies

A successful urban management system for a Ubiquitous Eco City requires an integrated approach. This integration includes bringing together economic, socio-cultural and urban development with a well orchestrated, transparent and open decision making mechanism and necessary infrastructure and technologies. Rapidly developing information and telecommunication technologies and their platforms in the late 20th Century improves urban management and enhances the quality of life and place. Telecommunication technologies provide an important base for monitoring and managing activities over wired, wireless or fibre-optic networks. Particularly technology convergence creates new ways in which the information and telecommunication technologies are used. The 21st Century is an era where information has converged, in which people are able to access a variety of services, including internet and location based services, through multi-functional devices such as mobile phones and provides opportunities in the management of Ubiquitous Eco Cities. This paper discusses the recent developments in telecommunication networks and trends in convergence technologies and their implications on the management of Ubiquitous Eco Cities and how this technological shift is likely to be beneficial in improving the quality of life and place. The paper also introduces recent approaches on urban management systems, such as intelligent urban management systems, that are suitable for Ubiquitous Eco Cities

The Impact Of Organizational Goal Convergence, Information-communication Technology Utilization, And Inter-organizational Trust On Network Formation And Sustainability The Case Of Emergency Management In The United States

With the increase of severity and scope of disasters, collaborative networks have become the main tool to tackle with complex emergencies. Networks, however, are mostly effective to the extent they are maintained over time. This study analyzes whether organizational goal convergence, information-communication technology utilization, and inter-organizational trust impacts network sustainability. The main research questions of the study are: (1) How are organizational goals, technical/technological capacity of organizations, and trust among organizations of a network are related to the sustainability of collaborative network relationships? (2) Which of the above-mentioned factors plays the most significant role in affecting network sustainability? Covering the context of emergency management system in the United States, this study utilized a self-administered survey that was electronically distributed to county emergency managers across the country. The data consisting of 534 complete responses was analyzed in Statistical Package for the Social Sciences (SPSS) Inc. software‟s PASW (Predictive Analytics SoftWare) Statistics version 18.0 and transferred to Amos 18.0 software for structural equation modeling (SEM) analysis. The findings suggest that organizational goal convergence, information-communication technology utilization, and inter-organizational trust have positive and statistically significant relationships with network sustainability; and, interorganizational trust is the strongest factor followed by information-communication technology utilization and organizational goal convergence. The study contributes to the literature on network sustainability with specific suggestions for emergency management practitioners
