Empowerment
This entry discusses the various roles of media and communication in terms of empowerment and social change. It does so by focusing on a temporal and historical dimension which relates to innovations in terms of media and communication technologies going from the print-press over radio broadcasting and the internet. Besides this, we also identify a special dimension going from the local to the trans-national, but also exposing media and communication as a space of contention. Finally, a strategic dimension is identified focusing on how political actors and social movements frame issues and attempt to influence, at times successfully at other times less so, the process of meaning making
Journalistic transgressions in the representation of Jeremy Corbyn: from watchdog to attack dog
This research critically assesses the press coverage of Jeremy Corbyn during his leadership bid and subsequent first months as the leader of the United Kingdom’s Labour Party. A content analysis (n = 812) found that the British press offered a distorted and overly antagonistic view of the long-serving MP. Corbyn is often denied a voice and news organisations tended to prize anti-Corbyn sources over favourable ones. Much of the coverage is decidedly scornful and ridicules the leader of the opposition. This analysis also tests a set of normative conceptions of the media in a democracy. In view of this, our research contends that the British press acted more as an attackdog than a watchdog when it comes to the reporting of Corbyn. We conclude that the transgression from traditional monitorial practices to snarling attacks is unhealthy for democracy, and it furthermore raises serious ethical questions for UK journalism and its role in society
When our watchdog becomes a bloodthirsty attackdog, be wary
Jeremy Corbyn has been variously described in the British press as unelectable, comic and highly dangerous. How should a healthy democracy respond to politicians pursuing a different kind of democracy

Investigating the reliability of coronal emission measure distribution diagnostics using 3D radiative MHD simulations
Determining the temperature distribution of coronal plasmas can provide
stringent constraints on coronal heating. Current observations with the Extreme
ultraviolet Imaging Spectrograph onboard Hinode and the Atmospheric Imaging
Assembly onboard the Solar Dynamics Observatory provide diagnostics of the
emission measure distribution (EMD) of the coronal plasma.
Here we test the reliability of temperature diagnostics using 3D radiative
MHD simulations. We produce synthetic observables from the models, and apply
the Monte Carlo Markov chain EMD diagnostic. By comparing the derived EMDs with
the "true" distributions from the model we assess the limitations of the
diagnostics, as a function of the plasma parameters and of the signal-to-noise
of the data.
We find that EMDs derived from EIS synthetic data reproduce some general
characteristics of the true distributions, but usually show differences from
the true EMDs that are much larger than the estimated uncertainties suggest,
especially when structures with significantly different density overlap along
the line-of-sight. When using AIA synthetic data the derived EMDs reproduce the
true EMDs much less accurately, especially for broad EMDs. The differences
between the two instruments are due to the: (1) smaller number of constraints
provided by AIA data, (2) broad temperature response function of the AIA
channels which provide looser constraints to the temperature distribution.
Our results suggest that EMDs derived from current observatories may often
show significant discrepancies from the true EMDs, rendering their
interpretation fraught with uncertainty. These inherent limitations to the
method should be carefully considered when using these distributions to
constrain coronal heating.Comment: Accepted for publication on The Astrophysical Journal. 25 pages, 29

Using Markov Models and Statistics to Learn, Extract, Fuse, and Detect Patterns in Raw Data
Many systems are partially stochastic in nature. We have derived data driven
approaches for extracting stochastic state machines (Markov models) directly
from observed data. This chapter provides an overview of our approach with
numerous practical applications. We have used this approach for inferring
shipping patterns, exploiting computer system side-channel information, and
detecting botnet activities. For contrast, we include a related data-driven
statistical inferencing approach that detects and localizes radiation sources.Comment: Accepted by 2017 International Symposium on Sensor Networks, Systems
