Coleridge: A computer tool for assisting musical reflection and self‐explanation
No full textThis paper examines some of the problems involved when learning how to compose music. A prototype computer‐based music tool called Coleridge is described. Coleridge was used in a study that investigated the dialogues that took place when a mentor attempted to encourage creative reflection in students. Results of dialogue analysis suggested that because learners seem unable to make accurate predictions about how a musical phrase will sound, there is a real need for a computer‐based learning assistant. Finally, the paper reports on how these findings were used to motivate the design of a mentor's assistant in a new version of Coleridge
The Writer Walking the Dog: Creative Writing Practice and Everyday Life
No full textCreative writing happens in and alongside the writer’s everyday life, but little attention has been paid to the relationship between the two and the contribution made by everyday activities in enabling and shaping creative practice. The work of the anthropologist Tim Ingold supports the argument that creative writing research must consider the bodily lived experience of the writer in order fully to understand and develop creative practice. Dog-walking is one activity which shapes my own creative practice, both by its influence on my social and cultural identity and by providing a time and space for specific acts instrumental to the writing process to occur. The complex socio-cultural context of rural dog-walking may be examined both through critical reflection and creative work. The use of dog-walking for reflection and unconscious creative thought is considered in relation to Romantic models of writing and walking through landscape. While dog-walking is a specific activity with its own peculiarities, the study provides a case study for creative writers to use in developing their own practice in relation to other everyday activities from running and swimming to shopping, gardening and washing up
Distributed human computation framework for linked data co-reference resolution
No full textDistributed Human Computation (DHC) is a technique used to solve computational problems by incorporating the collaborative effort of a large number of humans. It is also a solution to AI-complete problems such as natural language processing. The Semantic Web with its root in AI is envisioned to be a decentralised world-wide information space for sharing machine-readable data with minimal integration costs. There are many research problems in the Semantic Web that are considered as AI-complete problems. An example is co-reference resolution, which involves determining whether different URIs refer to the same entity. This is considered to be a significant hurdle to overcome in the realisation of large-scale Semantic Web applications. In this paper, we propose a framework for building a DHC system on top of the Linked Data Cloud to solve various computational problems. To demonstrate the concept, we are focusing on handling the co-reference resolution in the Semantic Web when integrating distributed datasets. The traditional way to solve this problem is to design machine-learning algorithms. However, they are often computationally expensive, error-prone and do not scale. We designed a DHC system named iamResearcher, which solves the scientific publication author identity co-reference problem when integrating distributed bibliographic datasets. In our system, we aggregated 6 million bibliographic data from various publication repositories. Users can sign up to the system to audit and align their own publications, thus solving the co-reference problem in a distributed manner. The aggregated results are published to the Linked Data Cloud
JFK: The Education of a President
No full textWhat goes into the making of a president? To what extent are the mind and character of the American commander in chief determined by his background, his family — and his education? This article represents a transcript of two lectures Nigel Hamilton presented in the spring and fall of 1989 at the Massachusetts State Archives. They were derived from the preliminary sketches for the author\u27s full-scale biography of John F. Kennedy, to be published by Houghton Mifflin in 1992 on the anniversary of the birth of the thirty-fifth president

Data-driven treatment selection for seamless phase II/III trials incorporating early-outcome data
No full textSeamless phase II/III clinical trials are conducted in two stages with treatment selection at the first stage. In the first stage, patients are randomized to a control or one of k > 1 experimental treatments. At the end of this stage, interim data are analysed, and a decision is made concerning which experimental treatment should continue to the second stage. If the primary endpoint is observable only after some period of follow-up, at the interim analysis data may be available on some early outcome on a larger number of patients than those for whom the primary endpoint is available. These early endpoint data can thus be used for treatment selection. For two previously proposed approaches, the power has been shown to be greater for one or other method depending on the true treatment effects and correlations. We propose a new approach that builds on the previously proposed approaches and uses data available at the interim analysis to estimate these parameters and then, on the basis of these estimates, chooses the treatment selection method with the highest probability of correctly selecting the most effective treatment. This method is shown to perform well compared with the two previously described methods for a wide range of true parameter values. In most cases, the performance of the new method is either similar to or, in some cases, better than either of the two previously proposed methods. © 2014 The Authors.

Post-war British working-class fiction with special reference to the novels of John Braine, Alan Sillitoe, Stan Barstow, David Storey and Barry Hines
No full textThis study is about British working-class fiction in the post-war period.
It covers various authors such as Robert Tressell, George Orwell, Walter Greenwood, Lewis Grassic Gibbon and DH Lawrence from the early twentieth century; writers traditionally classified as 'Angry Young Men' like John Osborne, Arnold Wesker, Shelagh Delaney, John Wain and
Kingsley Amis; and working-class novelists like John Braine, Stan Barstow, David Storey, Alan Sillitoe and Barry Hines from the 1950s and 1960s.
Some of the main issues dealt with in the course of this study are language, form, community, self/identity/autobiography, sexuality and relationship with bourgeois art. The major argument centres on two questions: representation of working-class life, and the
relationship between working-class literary tradition and dominant ideologies.
We will be arguing that while working-class fiction succeeded in challenging and rupturing bourgeois literary tradition, on the level of language and linguistic medium of expression for example, it utterly failed to break away from dominant, bourgeois modes of literary production in relation to form, for instance.
Our argument is situated within Marxist approaches to literature, a political and aesthetic position from which we attempt an analysis and an evaluation of this working-class literary tradition. These critical approaches provide us also with the theoretical tool to define the political perspective of this tradition, and to judge whether it was confined to a descriptive mode of representation or
located in a radical, political outlook
