Three experiments investigated the relationship between subjective experience and attentional lapses during sustained attention. These experiments employed two measures of subjective experience to examine how differences in awareness correspond to variations in both task performance and psycho-physiological measures . This series of experiments examine these phenomena during the Sustained Attention to Response Task . The results suggest we can dissociate between two components of subjective experience during sustained attention: task unrelated thought which corresponds to an absent minded disengagement from the (...) task and a pre-occupation with one's task performance that seems to be best conceptualised as a strategic attempt to deploy attentional resources in response to a perception of environmental demands which exceed ones ability to perform the task. The implications of these findings for our understanding of how awareness is maintained on task relevant material during periods of sustained attention are discussed. (shrink)

Does respect for autonomy imply respect for precedent autonomy? The principle of respect for autonomy requires us to respect a competent patient’s treatment preference, but not everyone agrees that it requires us to respect preferences formed earlier by a now‐incapacitated patient, such as those expressed in an advance directive. The concept of precedent autonomy, which concerns just such preferences, is problematic because it is not clear that we can still attribute to a now‐incapacitated patient a preference which that patient never (...) disaffirmed but can no longer understand. If we cannot make that attribution, then perhaps we should not respect precedent autonomy – after all, how can you respect patient autonomy by giving patients what they no longer want, even if they never disaffirmed those wants? I argue that whether an earlier preference can still be attributed to a now‐incapacitated patient depends on the reasons behind the preference, for a preference includes (and is not merely supported by) the reasons behind it. When the considerations that served as reasons no longer exist, neither does the preference which included those reasons. In particular, if the considerations that served as reasons for the patient exist only under conditions where the patient retains full mental capacity, then once that capacity is lost, so are those reasons and the preference based upon them. I use this analysis of precedent autonomy to ascertain the merits of various approaches to advance medical decisionmaking, including Nancy Rhoden’s approach, approaches based on a Parfitian personal identity analysis, approaches based on soft paternalism, and approaches based on the stability and longevity of preferences. Despite the apparent absurdity of respecting patient autonomy by giving patients what they no longer prefer but have never disaffirmed, I conclude with some programmatic remarks on when and why respect for (precedent) autonomy nonetheless requires us to respect former preferences.

The roots of cognitivism lie deep in the history of Western thought, and to develop a genuinely post-cognitivist psychology, this investigation goes back to presuppositions descended from Platonic/Cartesian assumptions and beliefs about the nature of thought.

With the current changes driven by the expansion of the World Wide Web, this book uses a different approach from other books on the market: it applies ontologies to electronically available information to improve the quality of knowledge management in large and distributed organizations. Ontologies are formal theories supporting knowledge sharing and reuse. They can be used to explicitly represent semantics of semi-structured information. These enable sophisticated automatic support for acquiring, maintaining and accessing information. Methodology and tools are developed for (...) intelligent access to large volumes of semi-structured and textual information sources in intra- and extra-, and internet-based environments to employ the full power of ontologies in supporting knowledge management from the information client perspective and the information provider. The aim of the book is to support efficient and effective knowledge management and focuses on weakly-structured online information sources. It is aimed primarily at researchers in the area of knowledge management and information retrieval and will also be a useful reference for students in computer science at the postgraduate level and for business managers who are aiming to increase the corporations' information infrastructure. The Semantic Web is a very important initiative affecting the future of the WWW that is currently generating huge interest. The book covers several highly significant contributions to the semantic web research effort, including a new language for defining ontologies, several novel software tools and a coherent methodology for the application of the tools for business advantage. It also provides 3 case studies which give examples of the real benefits to be derived from the adoption of semantic-web based ontologies in "real world" situations. As such, the book is an excellent mixture of theory, tools and applications in an important area of WWW research. * Provides guidelines for introducing knowledge management concepts and tools into enterprises, to help knowledge providers present their knowledge efficiently and effectively. * Introduces an intelligent search tool that supports users in accessing information and a tool environment for maintenance, conversion and acquisition of information sources. * Discusses three large case studies which will help to develop the technology according to the actual needs of large and or virtual organisations and will provide a testbed for evaluating tools and methods. The book is aimed at people with at least a good understanding of existing WWW technology and some level of technical understanding of the underpinning technologies (XML/RDF). It will be of interest to graduate students, academic and industrial researchers in the field, and the many industrial personnel who are tracking WWW technology developments in order to understand the business implications. It could also be used to support undergraduate courses in the area but is not itself an introductory text. (shrink)

Captured through the lenses of some of the leading names in photography, Cities on the Edge provides a fascinating insight into six of the world’s most ‘edgy’ cities. Published to coincide with ambitious international ‘Cities on the Edge’ cultural programme, Davies and his hand picked team of photographers provide an incredible visual journey through six cities sharing common cultural, historical, social and economic ties. They are all ports, cities with great histories, cities which have battled with their capital cities over (...) many centuries, cities famous for their creativity, humour, distinctiveness, love of football. They are also cities which are sometimes considered by their countrymen to be difficult and unruly. Beautiful, unnerving and often stark but always striking, Cities on the Edge is a visually stunning tale of six beautifully and contradictory cities placing their complicated histories in context with their place in the ‘New Europe’.

The largest source of new information about Graeco-Roman antiquity is from newly discovered inscriptions. Epigraphic information gained through use of new techniques and technologies is helping to reshape and extend our knowledge of the religious life, languages, populations, governmental systems, and economies of the Greek and Roman world.

Frank Walbank, a scholar of ancient Greek history best known for his commentary on Polybios, held the Chair of Latin at Liverpool University and was active in university administration. He was elected Fellow of the British Academy in 1953. Obituary by John Davies FBA.

The legendary Greek figure Orpheus was said to have possessed magical powers capable of moving all living and inanimate things through the sound of his lyre and voice. Over time, the Orphic theme has come to indicate the power of music to unsettle, subvert, and ultimately bring down oppressive realities in order to liberate the soul and expand human life without limits. The liberating effect of music has been a particularly important theme in twentieth-century African American literature. The nine original (...) essays in Black Orpheus examines the Orphic theme in the fiction of such African American writers as Jean Toomer, Langston Hughes, Claude McKay, James Baldwin, Nathaniel Mackey, Sherley Anne Williams, Ann Petry, Ntozake Shange, Alice Walker, Gayl Jones, and Toni Morrison. The authors discussed in this volume depict music as a mystical, shamanistic, and spiritual power that can miraculously transform the realities of the soul and of the world. Here, the musician uses his or her music as a weapon to shield and protect his or her spirituality. Written by scholars of English, music, women's studies, American studies, cultural theory, and black and Africana studies, the essays in this interdisciplinary collection ultimately explore the thematic, linguistic structural presence of music in twentieth-century African American fiction.

The Bianchi Identities relating asymmetric curvature to torsion are obtained as a new set of equations governing second-order curvature tensors. The usual contribution of symmetric curvature to the gravitational field is found to be a subset of these identities though with an added contribution due to torsion gradients. The antisymmetric curvature two-tensor is shown to be related to the divergence of the torsion. Using a model of particle-antiparticle pair production, identification of certain torsion components with electroweak fields is proposed. These (...) components obey equations, similar to Maxwell's, that are subsets of these linear Bianchi identities. These results are shown to be consistent with gauge and other previous analyses.
