This thesis presents the Anita Conti Mapping Server, a Web interface and infrastructure for the creation and presentation of maps using an active, pervasive,multidimensional, global context. For each user, the context contains the parameterizations for every component of the system. In addition, parts of a user???s context may be shared with other users, so that the actions of one user directly affect the look, feel and content of another user???s system, thereby giving new meaning to the term collaborative computing. The mapping server consists of a Web interface, the GMT mapping tools, a database and the Omega typesetting system. Instead of the components being directly attached to each other through point-to-point communication, they are brought together by the context. This approach provides much more flexbility, since new components and new parameters can be more easily added to the overall system, with little or no change to the components already present. The whole infrastructure is built using intensional programming, a form of programming in which software entities are considered to be intensions (in the logical sense), i.e. mappings from contexts to ordinary entities, called extensions. The thesis presents a comprehensive overview of the development of intensional programming, and highlights its relevance for current work in the areas of electronic documents and distributed software configuration management. The mapping server is the most significant intensional application to date: it contains the most number of lines of intensional code ever written with the biggest context space implemented in a real, working system. The thesis focuses on the parameterization of the Web interface, the mapping engine and the generation of correctly typeset labels for maps to create a parameter space that accurately describes these components, and how this parameter space as a whole can be browsed by a user independently or as a member of a collaborative group. This thesis is just the beginning of a new way to look at mapping and proves that focusing on the context allows the creation of powerful extensible software.

Purpose: This article is an overview of scholarly monographs on rock music from 1980 to the present. It provides an overview to the literature for practical purposes of collections development as well as giving the reader insight into key issues and trends related to a interdisciplinary topic that attracts scholars from many disciplines in the humanities and social sciences. Design/methodology/approach: This bibliographic essay, focusing on works related to American culture and of a general nature, includes an overview and historical background; a discussion of how music and ethnomusiciological scholars approach the topic; geographic approaches; literature on four key icons (Elvis, Dylan, Springsteen, and Madonna); American studies; subcultures and genres; other methodologies; and concludes by discussing notable recent works. Findings: The scholarly literature on rock incorporates a wide variety of approaches and methodologies. Many music-related scholars appropriate methodology from other disciplines and some non-music-related scholars use the formalistic analysis of music scholars. Authenticity is a major theme in the literature on rock. Originality/value: This essay covers the widest range of monographs on the topic, providing insight into not only the key scholars but also the diversity of approaches to the topic. The historical approach to the literature gives the reader a sense of how the academic discourse on rock has evolved. This essay is of interest to librarians, scholars of rock music, and others concerned with how American scholarship in the humanities and the social sciences has grown since the advent of cultural studies.

The primary purpose of this study was to determine if there is a relationship between the bibliographic citation practices of the members of a discipline and the emphasis placed on citation accuracy and purposes in the graduate instruction of the discipline.

Sol-gel matrices may be used to immobilise enzymes, facilitating retention of the catalyst while allowing a flow of substrates and products through the matrix. Candida antarctica lipase B (CALB), a commonly used industrial enzyme, has been shown to have a prolonged catalytic life and enhanced activity when encapsulated in these sol-gel materials. However, the molecular basis for this effect had yet to be elucidated. This study investigated the effect of encapsulating CALB in sol-gel matrices by comparison of CALB in solution with its encapsulated form. Use of complementary techniques revealed the presence of complex interactions between the enzyme and the evolving sol-gel material. 29Si Nuclear Magnetic Resonance (NMR) measurements demonstrated that CALB influenced sol-gel structure by altering silica speciation. Inclusion of CALB also altered the mesoporosity of the matrices as determined using nitrogen sorption and electron microscopy. Correlation of activity assays with 29Si speciation changes indicated that the catalytic activity of the enzyme in solution was directly involved in sol-gel hydrolysis and condensation reactions. Increased specific activity of CALB in the sol-gel aqueous precursor solution resulted in measurable changes in the gel structure of matrices containing 3.1mg of CALB/ml of gel. Small angle neutron scattering (SANS) was used to examine the structure of CALB in solution. The influence of the sol-gel reactants glycerol, sodium fluoride and isopropanol upon the radius of gyration of CALB in solution was determined. SANS was also employed in an investigation of encapsulated CALB molecules which utilised contrast matching of the sol-gel matrix. However, contrast variation studies found that the match point for the silica matrix, both with and without enzyme present, was lower than predicted (~35% vol% D2O). Consequently, the contrast match point of the protein was close to that of the encapsulating material. Scattering from the encapsulated protein at this point was therefore minimal; it is clear that the contrast match point of the protein should be moved through in vivo deuteration in future experiments of this type. These investigations advance the understanding of interactions between the matrix and the encapsulated enzyme in sol-gel biomaterials.

In the late twentieth century international trade moved from a political multi-polar system based on the nation-state to a system featuring unified regional trading regimes. An inevitable feature of increased cooperation through bilateral, regional and international arrangements is the emergence of disputes over the interpretation and implementation of the agreed upon commitments. Accordingly, reliable mechanisms for the settlement of trade related disputes have become necessary to ensure the effective and continued functioning of these arrangements. Over the years these dispute settlement mechanisms have evolved from the relatively simple, diplomacy based structures called for in the GATT, to the detailed, legalistic, adjudication based mechanism found in the WTO. Bilateral and regional initiatives, such as NAFTA and MERCOSUR, as well as the EU, have similarly adopted dispute settlement mechanisms which adopt, in varying degrees, legalistic adjudicatory processes. Since 1967 ASEAN has spearheaded the creation of a regional trading bloc in the South East Asian region. As in other trading blocs, this has inevitable led to the need to develop effective and workable dispute settlement mechanisms. This thesis examines the development of trade dispute settlement mechanisms in ASEAN tracing its development from a model based on pragmatic diplomacy to a legalistic adjudicatory system with particular reference to the ASEAN context. It examines the extent to which the ASEAN context has influenced the content and the adoption of trade dispute settlement mechanisms in the region, as well as the extent to which the recently adopted 2004 Enhanced Protocol on Dispute Settlement can adequately address trade disputes in the region while remaining sensitive and responsive to the ASEAN context. Based on a comparative examination of dispute settlement mechanisms in other trade agreements, a range of key procedural issues are identified and examined with a view to identifying the prospects and challenges which ASEAN faces in the implementation of its dispute settlement mechanism. The thesis analyses the prospects and challenges of implementation the 2004 Enhanced Protocol on DSM.
