Problems of Paraphrase: Bottom\u27s Dream

Philosophers and critics alike often contend that metaphors cannot or should not be paraphrased, ever. Yet a simple and decisive empirical argument — The Horse’s Mouth Argument—suffices to show that many metaphors can be paraphrased without violating the spirit in which they were put forward in the first place. This argument leaves us with urgent unanswered questions about the role of paraphrase in a more inclusive division of exegetical labor, about the tension between its notorious openendedness and its claim to restate something already stated, andabout the relation between the content of a paraphrase and the content (or contents) of the metaphor the paraphrase purports to explain. But it leaves us in a position to state such questions more clearly and hopefully than we could before

Process Evaluation of the Realising Ambition Programme

Launched in May 2012 by the Big Lottery Fund (hereafter 'the Fund'), the Realising Ambition programme aims to help more young people aged 8-14 fulfil their potential and avoid pathways into offending. It does this by supporting 25 organisations to replicate proven youth interventions at new sites across the UK. The Realising Ambition process evaluation covered the first three, of five, years of the programme (2012-2015). The process evaluation had two key objectives:* To gain an understanding of the practical issues associated with replication, including issues emerging for organisations involved in replication themselves.* To explore what does and doesn't work when supporting organisations to replicate proven models, and the resources required to support different approaches to replication

A novel asymptotic formulation for partial slip half-plane frictional contact problems

A method of solution and the necessary calibrations are given to permit the steady-state extent of slip to be found in contacts properly described within a half-plane formulation using only two parameters: the contact law and the first-order descriptions of tractions arising at the contact edges. The approach takes the assumption of full stick and corrects for the slip regions using an array of glide dislocations. This is a very versatile approach and is particularly appropriate when studying fretting fatigue, as it permits the region in which cracks nucleate to be defined very simply, and in a form which is transportable from contact to contact, including laboratory tests. The approach has the additional benefit of giving a relatively straightforward expression for the density of dislocations, from which the slip displacement and shear traction within the stick region may readily be calculated. An example implementation is provided in the case of a Hertzian contact in the absence of changes in bulk tension, for which we demonstrate the veracity of the predictions by comparing to previous asymptotic approaches that build upon the traction solution under the assumption of full sliding, as well as the known exact solution
