6C radio galaxies at z~1: The influence of radio power on the alignment effect

Powerful radio galaxies often display enhanced optical/UV continuum emission and extended emission line regions, elongated and aligned with the radio jet axis. The expansion of the radio source strongly affects the gas clouds in the surrounding IGM, and the kinematic and ionization properties of the extended emission line regions display considerable variation over the lifetime of individual sources, as well as with cosmic epoch. We present the results of deep rest-frame UV and optical imaging and UV spectroscopy of high redshift 6C radio galaxies. The interdependence of the host galaxy and radio source properties are discussed, considering: (i) the relative contribution of shocks associated with the expanding radio source to the observed emission line gas kinematics, and their effect on the ionization state of the gas; (ii) the similarities and differences between the morphologies of the host galaxies and aligned emission for a range of radio source powers; and (iii) the influence of radio power on the strength of the observed alignment effect.Comment: LaTeX, 6 pages, 5 figures, Elsevier Science format.

Upbeat and quirky with a bit of a build: Interpretive repertories in creative music search

Pre-existing commercial music is widely used to accom-pany moving images in films, TV commercials and com-puter games. This process is known as music synchronisa-tion. Professionals are employed by rights holders and film makers to perform creative music searches on large catalogues to find appropriate pieces of music for syn-chronisation. This paper discusses a Discourse Analysis of thirty interview texts related to the process. Coded ex-amples are presented and discussed. Four interpretive repertoires are identified: the Musical Repertoire, the Soundtrack Repertoire, the Business Repertoire and the Cultural Repertoire. These ways of talking about music are adopted by all of the community regardless of their interest as Music Owner or Music User. Music is shown to have multi-variate and sometimes conflicting meanings within this community which are dynamic and negotiated. This is related to a theoretical feedback model of communication and meaning making which proposes that Owners and Users employ their own and shared ways of talking and thinking about music and its context to determine musical meaning. The value to the music information retrieval community is to inform system design from a user information needs perspective

Organising music for movies

Purpose - The purpose of this paper is to examine and discuss the classification of commercial popular music when large digital collections are organised for use in films. Design/methodology/approach - A range of systems are investigated and their organization is discussed, focusing on an analysis of the metadata used by the systems and choices given to the end-user to construct a query. The indexing of the music is compared to a checklist of music facets which has been derived from recent musicological literature on semiotic analysis of popular music. These facets include aspects of communication, cultural and musical expression, codes and competences. Findings -In addition to bibliographic detail, descriptive metadata is used to organise music in these systems. Genre, subject and mood are used widely; some musical facets also appear. The extent to which attempts are being made to reflect these facets in the organization of these systems is discussed. A number of recommendations are made which may help to improve this process. Originality/value - This paper discusses an area of creative music search which has not previously been investigated in any depth and makes recommendations based on findings and the literature which may be used in the development of commercial systems as well as making a contribution to the literature

Content or context? Searching for musical meaning in task-based interactive information retrieval

Creative professionals search for digital music to accompany moving images using interactive information retrieval systems run by music publishers and record companies. This research investigates the creative professionals and the intermediaries communication processes and information seeking and use behaviour with a view to making recommendations to information retrieval systems builders as to the extent of relative importance of content and contextual factors. A communications model is used to suggest that the meaning of music is determined by its listener and use context, as well as cultural codes and competences. The research is framed by a holistic approach based on Ingwersen and Jarvelin’s Interactive Information Seeking, Retrieval and Behavioral processes model

Practitioner and LIS Student Perspectives on Information Literacy for Librarians

This paper considers recent findings of ongoing research exploring how Library and Information Studies education can most effectively support students in developing their information literacy instruction practices. Practicing librarians in the UK were interviewed in order to gather their insights on the development of their information literacy instruction skills. The analysis identified key concepts and issues which may help to inform curriculum development in information literacy in LIS education, which is a growth area in the UK

Music in the Movies: an investigation into Creative Music Search

Music is widely used to accompany moving images. Just turn on the television and shut your eyes to experience this. Movie soundtracks enhance the viewers experience, TV commercials use music to communicate brand values and attract the attention of the viewer, and TV programs feature a wide range of music throughout. Much of this music is not composed specifically for this purpose but has another life in the commercial market place. The owners of these recordings and compositions are making great efforts to secure a place for their music in these media and employ expert intermediaries to ‘place’ music in films and TV. Some collections are organised into B2B digital libraries specifically for this purpose, which is known as music synchronisation. Naturally, the collections are organised by traditional metadata such as Artist, Title, Album and Genre. However as users don’t always know exactly what they are looking for, but know what it should sound like, additional facets such as Mood, Tempo and Subject are also employed. In this presentation Charlie Inskip will discuss how creative search is facilitated by these search engines and whether they may be improved

Deep spectroscopy of a young radio source at z=0.521

9C J1503+4528 is a very young CSS radio galaxy, with an age of order 10^4 years. This source is an ideal laboratory for the study of the intrinsic host galaxy/IGM properties, radio source interactions, evidence for young stellar populations and the radio source triggering mechanism. Here we present the results of a spectroscopic analysis of this source, considering each of these aspects of radio source physics.Comment: 4 pages, 2 figures, to be published in Astronomische Nachrichte

Towards the disintermediation of creative music search: Analysing queries to determine important facets

Purpose: Creative professionals search for music to accompany moving images in films, advertising, television. Some larger music rights holders (record companies and music publishers) organise their catalogues to allow online searching. These digital libraries are organised by various subjective musical facets as well as by artist and title metadata. The purpose of this paper is to present an analysis of written queries relating to creative music search, contextualised and discussed within the findings of text analyses of a larger research project whose aim is to investigate meaning making in this search process. Method: A facet analysis of a collection of written music queries is discussed in relation to the organisation of the music in a selection of bespoke search engines. Results: Subjective facets, in particular Mood, are found to be highly important in query formation. Unusually, detailed Music Structural aspects are also key. Conclusions: These findings are discussed in relation to disintermediation of this process. It is suggested that there are barriers to this, both in terms of classification and also commercial / legal factors
