For the record

Discusses her film, For the Record, the making of which was funded by the Arts and Humanities Research Council. The research material used in the making of FOR THE RECORD consists of official records, private diaries, personal testimony, historical expert interviews and archive footage - all related to the Internment period 1956-1960 in Northern Ireland. Through the use of clips from the film and footage that did not make it into the final cut, this talk examines how selected material is used and to what purpose. FOR THE RECORD is a film about a daughter documenting a period in her father's life and centres on PJ McClean's prison diary, secretly written on the inside of envelopes during the first 30 days in his cell. This brings the viewer into the intimate space of personal testimony. This intimacy is also reflected in the interviews between father and daughter. Throughout the film the diaries are illustrated by experimental Super8 and 16mm footage shot by the filmmaker, over a period of 10 years, of home life. The film unravels the complex story of internment; the why, the how and the ‘for what’? Official records obtained from the Public Records Office Northern Ireland (which have been closed to the public for the past fifty years) combine with archive footage of the then Northern Irish Prime Minister, Basil Brookeborough, to give a wider political perspective to this personal testament. FOR THE RECORD deals with memory, memorabilia and the question of testimony in a complex political landscape. [From the Author]

Computational modeling of mold filling and related free-surface flows in shape casting: an overview of the challenges involved

Accurate representation of the coupled effects between turbulent fluid flow with a free surface, heat transfer, solidification, and mold deformation has been shown to be necessary for the realistic prediction of several defects in castings and also for determining the final crystalline structure. A core component of the computational modeling of casting processes involves mold filling, which is the most computationally intensive aspect of casting simulation at the continuum level. Considering the complex geometries involved in shape casting, the evolution of the free surface, gas entrapment, and the entrainment of oxide layers into the casting make this a very challenging task in every respect. Despite well over 30 years of effort in developing algorithms, this is by no means a closed subject. In this article, we will review the full range of computational methods used, from unstructured finite-element (FE) and finite-volume (FV) methods through fully structured and block-structured approaches utilizing the cut-cell family of techniques to capture the geometric complexity inherent in shape casting. This discussion will include the challenges of generating rapid solutions on high-performance parallel cluster technology and how mold filling links in with the full spectrum of physics involved in shape casting. Finally, some indications as to novel techniques emerging now that can address genuinely arbitrarily complex geometries are briefly outlined and their advantages and disadvantages are discussed.

FARM-Africa South Africa Northern Cape land reform and advocacy programme 2004-2008: final evaluation

FARM-Africa South Africa has played a crucial and important role in filling the gap that existed after the return of land to communities by government in the Northern Cape. Their support to farmer communities during the post-settlement phase has been critical for making productive use of land. During 2004-2008, FARM-SA has worked in 20 community projects in the Northern Cape, benefiting 745 poor households.
