āāFor you, pollutionā: The Victorian Novel and a Human Ecology. Disraeliās Sibyl and Gaskellās Mary Bartonā
Catherine Gallagher, in The Body Economic: Life, Death, and Sensation in Political Economy and the Victorian Novel locates the interest of Victorian literature in its deconstruction of boundaries. Her notion of a ādialectical synthesisā, in the novel, between Victorian political economy and āthe unique, nonfungible properties of thingsā and ānoninstrumental nature of peopleā (2006: 1) might, in turn, inform a less dichotomous ecological theory that would substitute (broadly) romantic, deep ecology with a more dialectical understanding in which the now recognised complexity of ecological systems would extend to encompass the human realm including, ultimately, issues around environmental injustice
The Benefit of Encoder Cooperation in the Presence of State Information
In many communication networks, the availability of channel state information
at various nodes provides an opportunity for network nodes to work together, or
"cooperate." This work studies the benefit of cooperation in the multiple
access channel with a cooperation facilitator, distributed state information at
the encoders, and full state information available at the decoder. Under
various causality constraints, sufficient conditions are obtained such that
encoder cooperation through the facilitator results in a gain in sum-capacity
that has infinite slope in the information rate shared with the encoders. This
result extends the prior work of the authors on cooperation in networks where
none of the nodes have access to state information.Comment: Extended version of paper presented at ISIT 2017 in Aachen. 20 pages,

Can Negligible Cooperation Increase Network Reliability?
In network cooperation strategies, nodes work together with the aim of
increasing transmission rates or reliability. This paper demonstrates that
enabling cooperation between the transmitters of a two-user multiple access
channel, via a cooperation facilitator that has access to both messages, always
results in a network whose maximal- and average-error sum-capacities are the
same---even when those capacities differ in the absence of cooperation and the
information shared with the encoders is negligible. From this result, it
follows that if a multiple access channel with no transmitter cooperation has
different maximal- and average-error sum-capacities, then the maximal-error
sum-capacity of the network consisting of this channel and a cooperation
facilitator is not continuous with respect to the output edge capacities of the
facilitator. This shows that there exist networks where sharing even a
negligible number of bits per channel use with the encoders yields a
non-negligible benefit.Comment: 27 pages, 3 figures. Submitted to the IEEE Transactions on
