Signs of the Times: Nineteenth - Twentieth Century Graffiti in the Farms of the Yorkshire Wolds
This paper is concerned with graffiti found in farm buildings on the Yorkshire Wolds, dating between the late nineteenth and late twentieth centuries. It uses an archaeological approach to explore the social and performative nature of these inscriptions, to analyse their content and character, and to consider the communities responsible for their creation. We argue that this was a vital medium of expression for a particular group of farm-workers – the horselads – and was part of the way in which they negotiated their status and identity during a period of great social upheaval and agricultural change (Giles and Giles 2007). We situate the making of these marks within the horselads’ seasonal rhythms of labour and broader patterns of inhabitation. Finally, we explore spatial and stratigraphic relationships associated with graffiti panels, to elucidate different groups within these communities, and analyse how they changed over time
Adjoint recovery of superconvergent functionals from PDE approximations
Motivated by applications in computational fluid dynamics, a method is presented for obtaining estimates of integral functionals, such as lift or drag, that have twice the order of accuracy of the computed flow solution on which they are based. This is achieved through error analysis that uses an adjoint PDE to relate the local errors in approximating the flow solution to the corresponding global errors in the functional of interest. Numerical evaluation of the local residual error together with an approximate solution to the adjoint equations may thus be combined to produce a correction for the computed functional value that yields the desired improvement in accuracy. Numerical results are presented for the Poisson equation in one and two dimensions and for the nonlinear quasi-one-dimensional Euler equations. The theory is equally applicable to nonlinear equations in complex multi-dimensional domains and holds great promise for use in a range of engineering disciplines in which a few integral quantities are a key output of numerical approximations
Water quality strategy for the Lockwoods Folly River: A partnership for an ailing river
As with a majority of the remaining undeveloped coastal areas in North Carolina, Brunswick County is not a hidden
treasure any more. Since 1980 the county’s population has more than tripled to over 95,000 and another 30,000 or so
residents are expected to make this last bastion of undeveloped southeastern NC their home by 2020, even with the current economic downturn.
As the 29th fastest growing county in the nation this population explosion is resulting in rapid landscape scale land use changes within the watershed of the Lockwoods Folly River. Subdivisions, shopping centers, new highways and bridges, golf courses, and marinas are becoming significant land use activities. The surging development within this 150-square mile 88 thousand-acre watershed has had a severe effect on the health of the river. The portion of the river closed to shell fishing has more that tripled from 18 percent in 1980 to more than 55 percent today and 60% of the beds are considered impaired. For generations, locals have enjoyed the bounty of the Lockwoods Folly River and estuarine system famed for its rich and abundant shell fish beds and excellent coastal inshore fishing. This river
system stretches from the Lockwoods Folly Inlet at the Atlantic Ocean inland where it makes the transformation
from saltwater marshes to a winding blackwater river that snakes into hundreds of smaller tributaries and blackwater
swamps. (PDF contains 4 pages
The future of the European Union : desmisting the debate
Includes "Notes on Contributors"Does Europe have a collective future, or will the coming years be marked by
increasingly incoherent developments within the heterogeneous EU? There is no
denying that the second decade of this century has seen a strong mood shift away
from the inter-dependence and concerted actions that guided Europe’s national
governments since the end of World War II, and then since the fall of the Berlin Wall.
What connections, if any, are there between the paroxysms of Brexit in the UK and
the varying shades of populism in continental Europe? The common denominator
may simply be the painful economic pressures resulting from waning global
competitiveness.
It is clear that the high ideals of the European project no longer exert the same
political pull. The EU’s dreams of progressing almost seamlessly from a trading zone
to a shared political economy are not being realised. Where are the convergence
policies that would exert centripetal rather than centrifugal forces? Where is the
appetite for reforms leading to political union, and whatever happened to the idea of
Europeans speaking with one voice?
If the EU continues along its present path, the verdict of history may well be that
it achieved little more than the welter of regulations needed to ensure trade flows. In
geopolitical terms, Europe as a major player on the world stage may have been an
illusion largely created by aggregating national statistics.peer-reviewe

A Story of Parametric Trace Slicing, Garbage and Static Analysis
This paper presents a proposal (story) of how statically detecting
unreachable objects (in Java) could be used to improve a particular runtime
verification approach (for Java), namely parametric trace slicing. Monitoring
algorithms for parametric trace slicing depend on garbage collection to (i)
cleanup data-structures storing monitored objects, ensuring they do not become
unmanageably large, and (ii) anticipate the violation of (non-safety)
properties that cannot be satisfied as a monitored object can no longer appear
later in the trace. The proposal is that both usages can be improved by making
the unreachability of monitored objects explicit in the parametric property and
statically introducing additional instrumentation points generating related
events. The ideas presented in this paper are still exploratory and the
intention is to integrate the described techniques into the MarQ monitoring
tool for quantified event automata.Comment: In Proceedings PrePost 2017, arXiv:1708.0688
Extending Honneth’s Shift in Focus for Critical Theory
Axel Honneth has called for a change of focus in Critical Theory "from the
self-generated independence of systems to the damage and distortion of
social relations of recognition." I argue that Honneth does not shift his
methodological focus sufficiently to succeed in his goal of illuminating
the social relations of recognition. Despite Honneth's shift to relations of
recognition, he considers these relations in terms of the macrosocial
Hegelian triad of social spheres of recognition. A deeper analysis of
recognition behaviors shows they cannot be mapped exactly to these
spheres. I conclude that the Hegelian triad of social spheres is an
insufficient basis for an exploration of misrecognition behaviors. To
understand misrecognition, we need to seek a picture of misrecognition
that reflects the complex diversity of individuals' lived experiences and
practices, gives sufficient attention to interpersonal recognition and
misrecognition, and offers potential reasons for why individuals might
engage in misrecognition behaviors
