Castells, ‘Murdochisation’, Economic Counterpower and Live-Streaming

In his Information Age trilogy, Manuel Castells documents the transformation of economic power by means of network affordances. In more recent work, he has built an account of the linking of economic power with cultural and political power through 'Murdochisation', or 'the networking of networks'. Whilst Castells’ account of power has thus developed to acknowledge the integration of economic, cultural and political interests and networks, his account of 'counterpower' remains largely focussed on cultural and political resistance in the form of protest. Here we explore a case of economic counterpower; the unauthorised live-streaming of digital sports broadcasts. Analysis of this particular case (of counterpower) is particularly significant given the centrality of ‘Murdochisation’ in Castells’ account of power in the network society. Emerging out of, alongside, and in response to the growth of Murdochised digital media sports networks, we explore the scope and limits of live-streaming as a form of economic counterpower and counter-Murdochisation. In this article, we document Castells’ theory of network power, the centrality of ‘Murdochisation’ to that account, and the centrality of monopoly control over digital sports broadcasting to Murdochised media empires. The scope and resilience of alternative streaming media in switching live sports programming from pay to view to free sharing is then examined. The failure to date of all attempts to prohibit free streams shows the on-going viability of such economic counterpower. However, whilst dominant actors cannot eliminate economic counterpower, where dominant actors choose not to broadcast, no switching of content can take place

Polaritonic molecular clock for all-optical ultrafast imaging of wavepacket dynamics without probe pulses

Conventional approaches to probing ultrafast molecular dynamics rely on the use of synchronized laser pulses with a well-defined time delay. Typically, a pump pulse excites a molecular wavepacket. A subsequent probe pulse can then dissociate or ionize the molecule, and measurement of the molecular fragments provides information about where the wavepacket was for each time delay. Here, we propose to exploit the ultrafast nuclear-position-dependent emission obtained due to large light–matter coupling in plasmonic nanocavities to image wavepacket dynamics using only a single pump pulse. We show that the time-resolved emission from the cavity provides information about when the wavepacket passes a given region in nuclear configuration space. This approach can image both cavity-modified dynamics on polaritonic (hybrid light–matter) potentials in the strong light–matter coupling regime and bare-molecule dynamics in the intermediate coupling regime of large Purcell enhancements, and provides a route towards ultrafast molecular spectroscopy with plasmonic nanocavitiesThis work has been funded by the European Research Council grant ERC-2016-STG-714870 and the Spanish Ministry for Science, Innovation, and Universities—AEI grants RTI2018-099737-B-I00, PCI2018-093145 (through the QuantERA program of the European Commission), and CEX2018-000805-M (through the María de Maeztu program for Units of Excellence in R&D

Heat and moisture exchangers (HMEs) and heated humidifiers (HHs) in adult critically ill patients: a systematic review, meta-analysis and meta-regression of randomized controlled trials

The aims of this systematic review and meta-analysis of randomized controlled trials are to evaluate the effects of active heated humidifiers (HHs) and moisture exchangers (HMEs) in preventing artificial airway occlusion and pneumonia, and on mortality in adult critically ill patients. In addition, we planned to perform a meta-regression analysis to evaluate the relationship between the incidence of artificial airway occlusion, pneumonia and mortality and clinical features of adult critically ill patients
