The digitization of music and the accessibility of the artist

©Journal of Professional Communication, ISSN: 1920-685. All rights reservedThis article uses case studies to explore two ways in which technology can impact on artist production. First, technological innovations could facilitate many things that are not new by rather making existing processes better or cheaper in ways that might alter the situation meaningfully. Second, technology can change art through the more profound revision of the role of artist and art-perceiver (Fineberg, 2006). This article examines several examples of how the music industry has been impacted by new technology: Radiohead Rainbows, slicethepie.com, Ditto Music, Music Rainbow, YouTube Orchestra, micro-chunking and LiveFi. The article examines the impact of new technologies on classical music.Peer reviewe

Status of LHCb

The status of the LHCb experiment is presented. The experiment has been taking data since the LHC startup. The performances of the various sub-detectors are discussed and a preliminary measurement of the b cross-section is reported. The value is in agreement with expectations.Comment: Proceedings of the HCP2010 Conference - Toronto - 201

Heterogeneity in R&D cooperation: an empirical investigation

This work explores the roles of potential simultaneity and heterogeneity in determining firms' decisions to engage in R&D collaboration, using a sample of Italian manufacturing firms. Partnerships with other firms, research institutions, universities and other small centres are considered jointly by applying a multivariate probit specification. This allows for systematic correlations among different cooperation choices. The results support the hypothesis that the four cooperation decisions are interdependent. The decision to cooperate in R&D differs significantly depending on the cooperation options. Public support, the researcher intensity and the size are all of importance in determining R&D alliance strategies

Inflation and output volatility under asymmetric incomplete information

The assumption of asymmetric and incomplete information in a standard New Keynesian model creates strong incentives for monetary policy transparency. We assume that the central bank has better information about its objectives than the private sector, and that the private sector has better information about shocks than the central bank. Transparency has the potential to trigger a virtuous circle in which all agents find it easier to make inferences and the economy is better stabilised. Our analysis improves upon existing work by endogenising the volatility of both output and inflation. Improved transparency most likely manifests itself in falling output volatility.

Grothendieck quasitoposes

A full reflective subcategory E of a presheaf category [C*,Set] is the category of sheaves for a topology j on C if and only if the reflection preserves finite limits. Such an E is called a Grothendieck topos. More generally, one can consider two topologies, j contained in k, and the category of sheaves for j which are separated for k. The categories E of this form, for some C, j, and k, are the Grothendieck quasitoposes of the title, previously studied by Borceux and Pedicchio, and include many examples of categories of spaces. They also include the category of concrete sheaves for a concrete site. We show that a full reflective subcategory E of [C*,Set] arises in this way for some j and k if and only if the reflection preserves monomorphisms as well as pullbacks over elements of E.Comment: v2: 24 pages, several revisions based on suggestions of referee, especially the new theorem 5.2; to appear in the Journal of Algebr
