Use and useability of learning objects within the COLIS demonstrator framework (Interaction of IT systems & repositories project report)
No full text[Executive Summary]: Murdoch University was one of several institutions and consortia funded to investigate the educational use of the Collaborative Online Learning and Information Services (COLIS) system developed in 2002 by a consortium based at Macquarie University. This project set out to investigate the use and useability of learning objects across three aspects of the COLIS system. Existing, single file learning objects were to be inserted into the IPR Systems Learning Object Exchange (LOX), transferred into the Learning Object Management System (LOMS), and made available through the WebCT Learning Management System. With the forced substitution of the Intralibrary Learning Object Repository for the IPR Systems exchange, the use of LOMS became superfluous. Similarly, the Federated search gateway did not function with the Intralibrary Learning Object Repository. Instead, Intralibrary’s own search function was used
The initial stages of development of the Carrick exchange
No full textThe development of the Carrick Exchange is a major initiative of the Carrick Institute for Learning and Teaching in Higher Education. The Carrick Exchange will combine a learning and teaching repository function with a Web 2.0 social networking capability 13 a MySpace for academics. It is aimed at those who teach, manage and lead in Higher Education in Australia. This paper reports on the initial stages of development. In particular, imaginary scenarios were used to envision the nature and the scope of the project. This work led to the identification of numerous human and technical issues which need to be addressed for the Carrick Exchange to be sustainable
Retrieval through explanation : an abductive inference approach to relevance feedback
No full textRelevance feedback techniques are designed to automatically improve a system's representation of a query by using documents the user has marked as relevant. However, traditional relevance feedback models suffer from a number of limitations that restrict their potential in supporting information seeking. One of the major limitations of relevance feedback is that it does not incorporate behavioural aspects of information seeking - how and why users assess relevance. We propose that relevance feedback should be viewed as a process of explanation and demonstrate how this limitation of relevance feedback techniques can be overcome by a theory of relevance feedback based on abductive inference
Use and usability of learning objects within the COLIS demonstrator framework
No full textMurdoch University was one of several institutions and consortia funded to investigate the educational use of the Collaborative Online Learning and Information Services (COLIS) system developed in 2002 by a consortium based at Macquarie University. This project set out to investigate the use and usability of learning objects across three aspects of the COLIS system. The major focus of this research was on the experience of the teacher in using learning objects within the COLIS framework.
Several activities took place. Librarians catalogued learning objects into the intraLibrary Learning Object Repository. Academic teaching staff searched for learning objects in intraLibrary and inserted them into WebCT. We investigated how easy it was for these stakeholders to use the suite of systems and identified ways in which both the systems and the processes around the systems might be improved
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Magnetic tunnel junctions with yttrium oxide barrier
No full textMagnetic tunnel junctions have been studied, with YOx barriers prepared by plasma oxidation of a 1.5 nm Y film. We report their junction area resistance, tunnel magnetoresistance (TMR) and barrier parameters (height and thickness) as a function of the oxidation time. For the optimum oxidation time, TMR values of similar to25% are obtained at room temperature and similar to44% at low temperature (5 K). The barrier height extracted from the current-voltage curves, is close to 1 eV, which is less than half of what is usually reported for AlOx-based junctions. Structural and topographical characterization of the multilayes revealed that the YOx layer is amorphous with well-defined, smooth, and correlated interfaces with the ferromagnetic electrodes.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Librarian’s Attitude Towards Information Communication Technology in Colleges Affiliated to Sant Gadge Baba Amravati University: A Study
No full textNow a day’s libraries have deployed the ICT facilities, along with high speed internet connectivity,photo- copiers, and soft copy drop facilities via USB drives, DVD R-W, micro SD drives, fax,scanners and computers. When all such facilities are backed by Government aids, the support of a
trained librarian having good orientation and attitude is very important. The organizational and infrastructural facilities and the service of library professionals are to go hand in hand to fully utilize ICT. The research findings reveal that lack of awareness and psychological barriers against advance technologies are the hurdles in providing ICT based LIS services
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
