Charabanc, cultural capital and the men of recognised credit

This paper compares the cultural legacy of the all-female Charabanc with that of Field Day, its fellow counterpart in the Irish Theatre touring movement in the 1980s. It suggests that a conscious awareness amongst the all-male Field Day board of successful writers and directors of what Bourdieu has called 'cultural capital' is implicated in the enduring authority of the work of that company within the history of Irish theatre. Conversely the paper considers if the populist Charabanc, in its steadfast refusal to engage with the hierarchies of academia and publishing, was too neglectful of the cultural capital which it accrued in its heyday and has thus been party to its own occlusion from that same history.

The rhetoric of acculturation: When integration means assimilation

Viewing traditional acculturation literature through a social constructionist lens, the present paper identifies a number of limitations with this research. A discourse analytic approach to acculturation is offered as a means of addressing some of these issues. Drawing on examples taken from British print media debate surrounding the issue of faith schooling in the UK, an analysis is presented which illustrates the manner in which, though optimally positioned within acculturative moral hierarchies directed towards the legitimization of both pro- and anti-faith schooling debates, integration rhetoric often conceals the (re-)production of a more implicit assimilationism. Findings are discussed in terms of their implications for hegemonically structured acculturative power relations. This exploratory analysis provides the basis for reflection on the benefits of a discursive approach to acculturation. Moreover, the dependence of integrationist discourse on a series of socio-spatial resources is considered and, following on from Dixon and Durrheim's (2000) discursive re-conceptualization of place-identity, is taken to signify the need for a more environmentally 'grounded' approach to acculturation.

Infinite Dimensional Banach spaces of functions with nonlinear properties

The aim of this paper is to show that there exist infinite dimensional Banach spaces of functions that, except for 0, satisfy properties that apparently should be destroyed by the linear combination of two of them. Three of these spaces are: a Banach space of differentiable functions on Rn failing the Denjoy-Clarkson property; a Banach space of non Riemann integrable bounded functions, but with antiderivative at each point of an interval; a Banach space of infinitely differentiable functions that vanish at infinity and are not the Fourier transform of any Lebesgue integrable function.

Valved Dataflow For FPGA Memory Hierarchy Synthesis

For modern FPGA, implementation of memory intensive processing applications such as high end image and video processing systems necessitates manual design of complex multilevel memory hierarchies incorporating off-chip DDR and onchip BRAM and LUT RAM. In fact, automated synthesis of multi-level memory hierarchies is an open problem facing high level synthesis technologies for FPGA devices. In this paper we describe the first automated solution to this problem.
By exploiting a novel dataflow application modelling dialect, known as Valved Dataflow, we show for the first time how, not only can such architectures be automatically derived, but also that the resulting implementations support real-time processing for current image processing application standards such as H.264. We demonstrate the viability of this approach by reporting the performance and cost of hierarchies automatically generated for Motion Estimation, Matrix Multiplication and Sobel Edge Detection applications on Virtex-5 FPGA.

Phylogeny versus body size as determinants of food web structure

Food webs are the complex networks of trophic interactions that stoke the metabolic fires of life. To understand what structures these interactions in natural communities, ecologists have developed simple models to capture their main architectural features. However, apparently realistic food webs can be generated by models invoking either predator-prey body-size hierarchies or evolutionary constraints as structuring mechanisms. As a result, this approach has not conclusively revealed which factors are the most important. Here we cut to the heart of this debate by directly comparing the influence of phylogeny and body size on food web architecture. Using data from 13 food webs compiled by direct observation, we confirm the importance of both factors. Nevertheless, phylogeny dominates in most networks. Moreover, path analysis reveals that the size-independent direct effect of phylogeny on trophic structure typically outweighs the indirect effect that could be captured by considering body size alone. Furthermore, the phylogenetic signal is asymmetric: closely related species overlap in their set of consumers far more than in their set of resources. This is at odds with several food web models, which take only the view-point of consumers when assigning interactions. The echo of evolutionary history clearly resonates through current food webs, with implications for our theoretical models and conservation priorities.

Autonomic management of non-functional concerns in distributed & parallel application programming

An approach to the management of non-functional concerns in massively parallel and/or distributed architectures that marries parallel programming patterns with autonomic computing is presented. The necessity and suitability of the adoption of autonomic techniques are evidenced. Issues arising in the implementation of autonomic managers taking care of multiple concerns and of coordination among hierarchies of such autonomic managers are discussed. Experimental results are presented that demonstrate the feasibility of the approach.

Scaling of the entanglement spectrum near quantum phase transitions

The entanglement spectrum describing quantum correlations in many-body systems has been recently recognized as a key tool to characterize different quantum phases, including topological ones. Here we derive its analytically scaling properties in the vicinity of some integrable quantum phase transitions and extend our studies also to nonintegrable quantum phase transitions in one-dimensional spin models numerically. Our analysis shows that, in all studied cases, the scaling of the difference between the two largest nondegenerate Schmidt eigenvalues yields with good accuracy critical points and mass scaling exponents.

Victims and Transitional Justice: Voice, Agency and Blame

This article explores the construction of victimhood in transitional societies. Drawn from fieldwork in a dozen jurisdictions as well as elements of criminological, feminist, sociological, philosophical and postcolonial literature, the article focuses in particular on how victimhood is interpreted and acted upon in transitional contexts. It explores the ways in which victims’ voice and agency are realised, impeded or in some cases co-opted in transitional justice. It also examines the role of blame in the construction of victimhood. In particular, it focuses upon the ways in which the importance of blame may render victimhood contingent upon ‘blamelessness’, encourage hierarchies between deserving and undeserving victims and require the reification of blameworthy perpetrators. The article concludes by suggesting that the increased voice and agency associated with the deployment of rights discourses by victims comes at a price – a willingness to acknowledge the rights and humanity of the ‘other’ and to be subject to the same respectful critical inquiry as other social and political actors in a post-conflict society.

Efficient tracking of human poses using a manifold hierarchy

In this paper a 3D human pose tracking framework is presented. A new dimensionality reduction method (Hierarchical Temporal Laplacian Eigenmaps) is introduced to represent activities in hierarchies of low dimensional spaces. Such a hierarchy provides increasing independence between limbs, allowing higher flexibility and adaptability that result in improved accuracy. Moreover, a novel deterministic optimisation method (Hierarchical Manifold Search) is applied to estimate efficiently the position of the corresponding body parts. Finally, evaluation on public datasets such as HumanEva demonstrates that our approach achieves a 62.5mm-65mm average joint error for the walking activity and outperforms state-of-the-art methods in terms of accuracy and computational cost.

Factors affecting the successful implementation and sustainability of the Liverpool Care Pathway for dying patients – a realist evaluation

Objectives: The Liverpool Care Pathway for the dying patient (LCP) was designed to improve end-of-life care in generalist health care settings. Controversy has led to its withdrawal in some jurisdictions. The main objective of this research was to identify the influences that facilitated or hindered successful LCP implementation.

Method: An organisational case study using realist evaluation in one health and social care trust in Northern Ireland. Two rounds of semi-structured interviews were conducted with two policy makers and twenty two participants with experience and/or involvement in management of the LCP during 2011 and 2012.

Results: Key resource inputs included facilitation with a view to maintaining LCP ‘visibility’, reducing anxiety among nurses and increasing their confidence regarding the delivery of end-of-life care; and nurse and medical education designed to increase professional self-efficacy and reduce misuse and misunderstanding of the LCP. Key enabling contexts were consistent senior management support; ongoing education and training tailored to the needs of each professional group; and an organisational cultural change in the hospital setting that encompassed end-of-life care.

Conclusion: There is a need to appreciate the organizationally complex nature of intervening to improve end-of-life care. Successful implementation of evidence-based interventions for end-of-life care requires commitment to planning, training and ongoing review that takes account of different perspectives, institutional hierarchies and relationships and the educational needs of professional disciplines. There is a need also to recognise that medical consultants require particular support in their role as gatekeepers and as a lead communication channel with patients and their relatives.

Organising EU non-discrimination law around the nodes of ‘race’ gender and disability?

EU non-discrimination law has seen a proliferation of discrimination grounds from 2000. Dis-crimination on grounds of gender (in the field of equal pay) and on grounds of nationality (generally within the scope of application of EU law) were the only prohibited forms of discrimination in EU law, until the Treaty of Amsterdam empowered the Community to legislate in order to combat discrimination on grounds of sex, racial or ethnic origin, religion or belief, disability, age or sexual orientation (Article 13 EC). Proliferation of non-discrimination grounds is also characteristic for international and national non-discrimination law. As such, proliferation of grounds results in an increase in potential cases of “multiple discrimination” and the danger of diluting the demands of equality law by ever more multiplication of grounds. The hierarchy of equality, which has been so widely criticised in EU law, is a signifier of the latter danger.
This chapter proposes to structure the confusing field of non-discrimination grounds by organising them around nodes of discrimination fields. It will first reflect different ways of establishing hierarchies between grounds. This will be followed by a recount of different (narrow and wide) reading of grounds. A comprehensive reading of the grounds gender, ‘race’ and disability as establishing overlapping fields of discrimination grounds will be mapped out, with some examples for practical uses.

New Irish speakers and the ‘gaelicisation’ of Belfast

New Irish speakers in Belfast play a crucial, complex part in the revitalization and change of both the city and Irish within Northern Ireland. This paper examines the role of new Irish speakers in transforming Belfast, whose emergence from a post-conflict period involves a reassessment of communal cultural expressions. Markers of ethno-national identity are bitterly contentious locally, and yet increasingly celebrated, in line with international trends, as high status cultural forms and potentially profitable tourist attractions. Irish in Belfast currently occupies an ambiguous position: divisive enough for a sign reading ‘Happy Christmas’ in Irish to be experienced as an insult by some city councillors, yet a secure enough part of the establishment for a neighbourhood to be officially rebranded as the Gaeltacht Quarter.
When, how and where new Irish speakers use the language in Belfast has implications for the relationship of Irishness to the Northern Irish state and for the place of Belfast within regional frameworks across the UK, Ireland and Europe. Adult learners and young people exiting Irish medium education have an impact on life in Belfast beyond its small population of Irish speakers. Urbanisation fuelled by new speakers, which shifts the balance of Irish language resources and speakers away from traditional rural Gaeltacht areas and towards cities, also has implications for the language itself. Recent increase in new Irish speakers in Belfast is due to expansion in the Irish-medium sector as well as to adult learners, whose decisions contribute to the school expansion.
Urbanisation, multilingualism and intergenerational shift combine in Belfast to produce new linguistic norms. Moreover, in a minority language community where hierarchies of ‘authenticity’ are weighted towards the rural and the native speaker, where the rural and the native have traditionally been conflated, and where indigeneity is a central concept to contested nationalisms, the emergence of a self-confident, youthful Irish speaking community in Northern Ireland’s biggest city involves a recalibration of the qualities signifying ‘gaelicness’. As students, professionals, hobbyists and activists, new Irish speakers in Belfast occupy a vital position at the crux of changing ideas about place, language and identity.

Stability in a Network Economy: The Role of Institutions

We consider an economy in which agents are embedded in a network of potential value-generating relationships. Agents are assumed to be able to participate in three types of economic interactions: Autarkic self-provision; bilateral interaction; and multilateral collaboration through endogenously provided platforms.
We introduce two stability concepts and provide sufficient and necessary conditions on the network structure that guarantee existence, in cases of the absence of externalities, link-based externalities and crowding externalities. We show that institutional arrangements based on socioeconomic roles and leadership guarantee stability. In particular, the stability of more complex economic outcomes requires more strict and complex institutional rules to govern economic interactions. We investigate strict social hierarchies, tiered leadership structures and global market places.

Memory-centric VDF Graph Transformations for Practical FPGA Implementation

Realising memory intensive applications such as image and video processing on FPGA requires creation of complex, multi-level memory hierarchies to achieve real-time performance; however commerical High Level Synthesis tools are unable to automatically derive such structures and hence are unable to meet the demanding bandwidth and capacity constraints of these applications. Current approaches to solving this problem can only derive either single-level memory structures or very deep, highly inefficient hierarchies, leading in either case to one or more of high implementation cost and low performance. This paper presents an enhancement to an existing MC-HLS synthesis approach which solves this problem; it exploits and eliminates data duplication at multiple levels levels of the generated hierarchy, leading to a reduction in the number of levels and ultimately higher performance, lower cost implementations. When applied to synthesis of C-based Motion Estimation, Matrix Multiplication and Sobel Edge Detection applications, this enables reductions in Block RAM and Look Up Table (LUT) cost of up to 25%, whilst simultaneously increasing throughput.
