    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.

    Extending Honneth’s Shift in Focus for Critical Theory

    Get PDF
    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

    A Story of Parametric Trace Slicing, Garbage and Static Analysis

    Full text link
    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

    Us, Them, and Me! Intergroup and personal challenges of aging successfully

    Get PDF
    This Keynote Address was delivered at the 73 rd . Annual New York State Communication Association Conference on October 16, 2015. After an anecdotal foray into how he came to study “geronto-communication”, Dr. Giles reviewed his and others’ research and theory on the interfaces between intergenerational communication, subjective health, and aging across many Western and Asian settings. This programmatic body of work was, in large part, guided by communication accommodation theory (which was briefly overviewed). Thereafter, Dr. Giles introduced various views of successful aging and the role of communication practices therein. This led to the formulation and testing of a new theoretical framework, the communication ecology model of successful aging. The thrust of this work is even more poignant as lifespan boundaries and expectations are being incrementally extended
