...anche se non ho letto il rapporto McKinsey, come economista non posso mancare ad aggiungere un piccolo contributo alla discussione senza dubbio affascinante... cercando qua e la su internet lavori sul tema vi consiglio il seguente link http://www.mcrit.com/espon_scenarios/files/DOCUMENTS/eur20258en.pdf Ecco un estratto illuminante: Various compensation mechanisms mediate the impacts that productivity-augmenting innovations have on employment and productivity. Product innovations tend to improve employment, but the net effect depends on the extent to which new products replace existing products in the marketplace. Although process innovations usually involve the displacement of workers, they may also reduce unit costs of production and – in a competitive market – this effect is translated into decreasing prices that stimulate demand and employment. In a concentrated oligopolistic market decreasing costs are more likely to be translated into higher profits and wages depending on the bargaining power of trade unions, but even in this case aggregate demand and employment may be increased. It is possible to discern altogether six compensation routes that alleviate the labour-saving effects of technology-induced productivity enhancements (see Vivarelli 1995; Vivarelli and Pianta 2000): • via new machines (more jobs in the capital sector) • via decreases in prices (the number of new jobs depends on the degree of competition) • via new investments (the delay depends on the expectations of entrepreneurs) • via new consumption (the technological rent is partially appropriated by wages) • via new products (welfare vs. substitution effect) • via a decrease in wages (labour market adjustment triggered by technological unemployment that has a negative effect on aggregate demand) The actual difference between the labour-saving effects of on-going process innovations and the employment-creating impacts of product innovations varies considerably according to prevailing conditions of competition, price and wage rigidities, investment climate, and so on. Moreover, new technologies differ as to their propensity to create employment opportunities. For instance, the introduction of the automobile had a much higher effect on labour demand than the diffusion of the home computers.

Eurovisioni: la TV non è il web
by Blengino Nov. 4, 2011

Nov. 4, 2011

Quindici giorni fa, in missione per conto di Nexa sono stato al Festival Eurovisioni Xxv Festival Internazionale di Cinema e Televisione. Ho assistito alla presentazione della televisione ibrida HBBTV. Ho capito alcune cose utili sulle connect TV ed ho intuito alcuni pericoli per la rete. Ho anche assistito di persona ad una relazione del Commissario AGCOM Antonio Martuscello, ed è stato un momento davvero intenso, sebbene abbia potuto condividere il mio sconcerto con poche persone illuminate presenti al convegno. In generale il mondo della televisione presente in sala ha molto apprezzato il Martuscello-pensiero. Per quel che vale, alcune considerazioni di quella giornata li ho messi qui: http://bit.ly/vhiDNB (sono diventato un blogger ;-)! ) Da quel che ho capito (non essendo un tecnico), le connect Tv porranno in futuro problemi sulla netneutrality.

Fwd: [webscience-announce] ACM WebSci'12 Call for Papers
by J.C. DE MARTIN Nov. 3, 2011

Nov. 3, 2011

-------- Original Message -------- Subject: [webscience-announce] ACM WebSci'12 Call for Papers Date: Thu, 3 Nov 2011 18:00:14 +0000 From: Susan Davies <sdd(a)ecs.soton.ac.uk> To: 'webscience-announce(a)ecs.soton.ac.uk' <webscience-announce(a)ecs.soton.ac.uk> *4th ACM Web Science Conference (WebSci'12)* *June 22-24, 2012, Northwestern University, Evanston, Illinois* *Call for Papers* Web Science embraces the study of the Web as a vast information network of people and communities. It also includes the study of people and communities using the digital records of user activity mediated by the Web. An understanding of human behavior and social interaction can contribute to our understanding of the Web, and data obtained from the Web can contribute to our understanding of human behavior and social interaction. Accordingly, Web Science involves analysis and design of Web architecture and applications, as well as studies of the people, organizations, and policies that shape and are shaped by the Web. To address these diverse goals, the Web Science conference is inherently interdisciplinary, integrating computer and information sciences, communication, linguistics, sociology, psychology, economics, law, political science, and other disciplines. This conference is unique in the manner in which it brings these disciplines together in creative and critical dialogue, and we invite papers from all the above disciplines, as well as those that cross traditional disciplinary boundaries. Following the success of WebSci'09 in Athens, WebSci'10 in Raleigh, and WebSci'11 in Koblenz, we are seeking papers and research notes that describe original research, analysis, and practice in the field of Web Science, as well as extended abstracts that discuss novel and thought-provoking ideas and works-in-progress. Possible topics for submissions include, but are not limited to, the following: - Analysis of human behavior and social interaction using data from social media, online networks and communities - Methodological challenges of analyzing Web-based large-scale human interaction and behavior - Network analysis of the Web - Microlevel processes and interactions on the Web - Collective intelligence, collaborative production, and social computing - Structure and organization on the Web - Web communities and online lifestyles - Web, society, and innovation - Intellectual property and the commons - Governance, trust, and privacy - Web access, literacy, and democracy - Knowledge, education, and scholarship on and through the Web - People-driven Web technologies, including social search, open data, and new interfaces - Using the digital records of user activity mediated by the Web - New research questions and thought-provoking ideas, emphasizing the intersection of design and social interaction *Submission* Web Science is a strongly interdisciplinary field, with areas representing different traditions for conferences and publications. Therefore this year we are providing three different submission formats (papers, notes, and abstracts) to allow for a wide range of submissions from all disciplines relevant for Web Science. *Submission Guidelines for Research Papers & Research Notes* Research papers and research notes should present new results and original work that has not been previously published. Research papers should present significant theoretical, empirical, methodological, or policy-oriented contributions to research and/or practice. Research notes should describe brief and focused research contributions that are noteworthy. Papers can be up to 10 pages; notes up to 4 pages. All submissions should be formatted according to the official ACM SIG proceedings template (WebSci archive format at http://chi2012.acm.org/cfp-formatting-instructions.shtml#extendedformat) and submitted via EasyChair. *Submission Guidelines for Extended Abstracts* Extended abstracts should describe either (1) thought-provoking ideas with the potential for interesting discussions at the conference, or (2) works-in-progress for sharing valuable ideas, eliciting feedback on early-stage work, or fostering discussions and collaborations among colleagues. Extended abstracts can be up to 6 pages, and should be formatted according to the official ACM SIG abstract template (extended abstract format at http://chi2012.acm.org/cfp-formatting-instructions.shtml#extendedformat) and submitted via EasyChair. *Review, Publication, and Presentation* The Web Science program committee consists of a senior program committee that covers all relevant areas of Web Science as well as regular program committee members from these areas. Each submission will be refereed by at least 3 PC members and one senior PC member, to cover both the research background of each submission as well as the necessary interdisciplinary aspects. Review criteria for all types of submissions include significance, originality, presentation, validity, and the ability to stimulate discussion, with different emphases depending on the submission category to allow for consideration of all relevant works contributing to the advancement of Web Science. All accepted papers, notes, and extended abstracts will appear in the Web Science 2012 Conference Proceedings and will also be available through the ACM Digital Library, in the same length and format of the submission. Regardless of the submission format, accepted submissions will be presented in one of three formats: 1) as a 20-minute presentation followed by discussion, 2) during one of the poster presentations and discussion sessions, 3) or as part of a panel discussion. Research papers, research notes, and extended abstracts are eligible for presentation in any of the three formats, depending on reviewer recommendations. Submissions that are thought-provoking and novel will be more appropriate for longer presentation, while those that are expected to stimulate discussion will be ideal for presentation in smaller groups or as posters. *Deadlines* February 12: Submissions of papers and notes due February 26: Submissions of extended abstracts due March 31: Notification of acceptance April 29: Final versions of papers, notes, and extended abstracts due June 22-24: Web Science 2011 Conference, Evanston, Illinois, USA *General Chair* Noshir Contractor, Northwestern University, US *Program Chairs* Michael Macy, Cornell University, US Wolfgang Nejdl, L3S Research Center, Germany Website http://www.websci12.org/

http://pogue.blogs.nytimes.com/2011/11/03/amazon-lights-the-fire-with-free-… Secondo me un giorno gli storici dell'innovazione (e anche gli antropologi, gli psicologi, i sociologi, gli economisti, ecc. ecc.) studieranno il periodo 1995-2015 (date prese a spanne) e si chiederanno stupiti per quale astruso motivo i detentori dei diritti - case discografiche, case editrici, giornali, ecc. - hanno mostrato, in media, una così spiccata riluttanza a cogliere le occasioni offerte dalla tecnologia o, per lo meno, a sperimentare nuovi modi per commercializzare e diffondere i loro prodotti, preferendo piuttosto combattere sanguinose battaglie contro i loro stessi utenti. juan carlos
