Bookwork: “Lure” “Brisées”
No full textResearch ContextThe works were made since 2011 as an enquiry into the local, rural landscape, both agricultural and managed forest environments, near to the artists home in Raglan, South Wales. The research developed from the artist’s ongoing engagement with the relationships and convergences of landscape and technology from a gendered perspective which formed her critical context PhD by practice at University of Wales Newport in 2009.Research ImperativesThe underlying research question was: how does the “walked” or “felt” landscape, as opposed to the landscape of the technical sublime and the virtual environment, influence the point of view of the viewer and their location in relation to the image/object/video
Urban Population Distribution Models and Service Accessibility Estimation
No full textThis paper examines the influence of alternative population distribution models on GIS-based spatial accessibility analyses using the two-step Floating Catchment Analysis technique. Two population models were tested: the de facto standard of even-distribution within census tracts and a dasymetric-based approach. The latter builds on previous research through the use of a novel methodology that integrates raster map data with a recently built mailing information database in order to enhance the precision with which residential areas are identified. Analysis was conducted for a case study area (Cardiff, South Wales) in order to examine variations in accessibility to a number of public services in the city. The dasymetric model showed a general tendency to report lower accessibility scores, but detailed patterns depended on local factors and, to some extent, on modelling assumptions and methodological issues. A paired T-Test analysis demonstrated that significant differences in outcomes were dependant on the population model adopted. Accessibility-based measures are increasingly being incorporated into deprivation indicators and the paper concludes by suggesting that, if such analysis is to inform urban planning, local service provision and the spatial allocation of financial resources, greater attention needs to be given to the method of population representation utilised in such models
A Way of life, British cinema and new British identities.
No full textAn article that uses Amma Asante’s film A Way of Life as the main focus of how contemporary cinema in Wales and, to some extent Scotland and Ireland, has begun to open up questions around postcolonial identity at the British ‘margins’. Asante’s film centres on a racist murder in the South Wales Valleys and raises vital and interesting questions about not only race, but gender as components of contemporary Welsh identity. A Way of Life will be examined in the context of other examples of recent British cinema such as Ken Loach’s Ae Fond Kiss, which draws on the diverse ethnicity of contemporary Glasgow in a post 9/11 context in order to understand some of the ways that cinema is seeking to make sense of a fracturing British identity and Perry Ogden’s Pavee Lackeen, a study of a traveller family living on the margins of Ireland’s so-called Celtic Tiger economy
Deep Field
No full textA closely integrated poetry collection in several long sequences in which Philip Gross explores the issues raised by his father’s loss of language to deafness and aphasia in old age. His father was a wartime refugee from Estonia and formerly spoke four or five languages. The poems weave personal biography with an examination of voice, of language and identity, further developing the themes of Gross’s T.S.Eliot-prize-winning collection The Water Table
Elizabeth Edwards
No full textAdditional Information:A critical overview on the writings of Elizabeth Edwards. Particular attention is given to her methodological approach to examining cross-cultural visual histories, photographs as material culture and the history of collecting and institutional practices. The essay charts an evolving critical sensibility drawing on analytical methods from historiography, anthropology, cultural geography and museology, to explore photography as a complex material and visual artefact and its place in the historical imagination. This connects with Roberts’ own curatorial research on the archive and past collaboration with Edwards (Roberts, R. “In Visible Light”, 1997)The importance of Fox-Talbot’s writings is reviewed in proximity to his pioneering experiments that laid the foundations of modern photography and constituted the earliest serious cultural reflection on the origins and potential of the new medium. The essay emphasises the various roles and identities Talbot’s writing on photography embodies and his evolving pictorial and phenomenological response to his discovery from his seminal text The Pencil of Nature (1844-46), to lesser-known writings from personal correspondence and journals that connect with his conception and practice of photography. The essay builds on Roberts’ research into histories of photography and the work of Talbot in particular (Roberts, R. et al, “Huellas de Luz . Traces of Light”, Museo Naçional Centro de Arte Reina Sofia, 2001
Mass Observation: This is Your Photo
No full textResearch ContextThe central premise of Roberts’ research is that the work of the curator, especially when undertaken in a self-conscious and to some extent reflexive mode, embodies equivalent research dimensions to the work of the artist and the writer. The exhibition is the primary form and realisation of the research. Catalogues, books, essays, conferences and symposia surrounding it are vital parts of the critical context. They are conceived in parallel and ground the research beyond what is initially a dialogue between images, objects and ideas.Research ImperativesThe exhibition explores the historical and contemporary importance of Mass Observation (MO) through its archive. It marks on-going research exploring the archival imagination and the multiple rôles of photography in shaping social evidence and historical consciousness
Understanding dignity and care: an exploratory qualitative study on the views of older people of African and African-Caribbean descent
No full textPurpose
– The purpose of this paper is to report on a qualitative exploratory study conducted in Wales to explore what dignity and care mean from the perspectives of men and women aged 50 years and older who self‐identified as being either African‐Caribbean/West Indian, or Black Welsh (third‐ or fourth‐generation, with links to Africa or the Caribbean).
Design/methodology/approach
– Twenty‐one semi‐structured interviews were undertaken, allowing for the collection of data on the participants' understanding of dignity (what it is, and what it “looks and feels like”) and of care.
Findings
– Dignity and respect for older people are revealed to be key aspects of the participants' personal value systems. The notion of care is understood as “caring about” and is seen to be a key indicator of dignity. Moreover, both care and dignity were understood and, for many of the participants, were both conceptualised on a personal basis and shaped by a sense of identity that was, in part and to varying extents, communally mediated and rooted in a cultural collectivistic value orientation. The findings also reveal the intersections of care and minority ethnicity, and how – to varying extents – these intersections shape the participants' perceptions of how they are recognised and acknowledged in encounters where dignity is especially important, such as in the receiving of care. With these perceptions come various levels of engagement, avoidance or acceptance of the need for extra care or support.
Originality/value
– Exploratory in nature, this study investigates the importance of paying attention to the impact that cultural and ethnic identity (and accompanying belief systems) may have on how notions of dignity and of care (both personal and communally mediated) are understood. It seeks to contribute to the body of evidence on ways of working with “seldom‐heard” groups and the importance of building trust and establishing long‐term, community‐based research networks.Welsh Governmen
A unified approach to network traffic and network security visualisation
No full textIn this paper we present an architecture which enables data-sharing between computer security and network traffic visualisation tools. At its core is a middleware which manages all interactions. This enables one application to determine the acceptable input for another, and send compatible data. The middleware sits atop a unified database which provides data in a generic form to the applications. Interesting traffic patterns or attack trends seen in one tool can be sent directly to another for further examination and analysis. All communication in the middleware is performed using XML as a data transport mechanism
Numerical simulation of non-Newtonian fluid flow in mixing geometries
Get PDFIn this thesis, a theoretical investigation is undertaken into fluid and mixing flows generated by various geometries for Newtonian and non-Newtonian fluids, on both sequential and parallel computer systems. The thesis begins by giving the necessary background to the mixing process and a summary of the fundamental characteristics of parallel architecture machines. This is followed by a literature review which covers accomplished work in mixing flows, numerical methods employed to simulate fluid mechanics problems and also a review of relevant parallel algorithms. Next, an overview is given of the numerical methods that have been reviewed, discussing the advantages and disadvantages of the different methods. In the first section of the work the implementation of the primitive variable finite element method to solve a simple two dimensional fluid flow problem is studied. For the same geometry colour band mixing is also investigated. Further investigational work is undertaken into the flows generated by various rotors for both Newtonian and non-Newtonian fluids. An extended version of the primitive variable formulation is employed, colour band mixing is also carried out on two of these geometries. The latter work is carried out on a parallel architecture machine. The design specifications of a parallel algorithm for a MIMD system are discussed, with particular emphasis placed on frontal and multifrontal methods. This is followed by an explanation of the implementation of the proposed parallel algorithm, applied to the same fluid flow problems as considered earlier and a discussion of the efficiency of the system is given. Finally, a discussion of the conclusions of the entire accomplished work is presented. A number of suggestions for future work are also given. Three published papers relating to the work carried out on the transputer networks are included in the appendices
A hybrid mathematical model of fungal mycelia : tropisms, polarised growth and application to colony competition
Get PDFFungi are a crucial component of most ecosystems and are responsible for decomposing organic
matter, distributing nutrients through the environment and supporting plants and animal life
through symbiotic relationships. Certain species of fungi are common pathogens causing disease
and infection in plants and animals. The highly integrated nature of fungi in relation to the
environment and all life emphasises the importance of developing a greater understanding of the
growth and morphology of such organisms.
Mathematical modelling has provided a means through which key processes can be isolated
to analyse and simulate a target system to allow observations and form predictions regarding
unknown phenomena. Numerous models of fungal colonies have been produced and are generally
categorised into two main groups; continuous and discrete. The following study combines the
approaches so that the constructed hybrid model comprises a discrete network that represents the
fungal mycelia and a continuous component to account for the continuous substrates and other compounds crucial to fungal growth and development. Key processes such as uptake, translocation
and anastomosis are included in addition to the implementation of a flexible hyphal orientation
scheme that facilitates a variety of tropisms to different influential factors.
The hybrid model is used to investigate several scenarios such as the polarisation of growth in
response to isolated nutrient resources, competition between multiple colonies and fungal development
and persistence in polluted environments. These investigations demonstrate the versatility
of the hybrid model and highlight the potential for further applications
