Item Digital Libraries as Learning Environments: A Case for Enabling Digital Libraries(2005-08-10T13:02:59Z) Ahmad, FaisalItem Digital Libraries as Learning Environments: A Case for Enabling Digital Libraries(2005-08-10T12:57:13Z) Ahmad, FaisalDigital libraries have improved the availability of resources by leaps and bonds compared to traditional libraries. The improved availability does not have much effect on improved accessibility of resources. Accessibility is related to making the resources useable and useful for the user [1]. This shortcoming can be addressed by changing the focus from user-centered design to learner-centered design of digital libraries. In this paper, I present a theory of learning that is a natural fit for online digital libraries. Based on this theory, I will present a framework that provides guidance for design and development of educational digital libraries. I call the resulting digital libraries “Enabling Digital Libraries”. Enabling digital libraries are characterized by the interactions that provide processes and representations that enable a learner to grasp a higher level of understanding related to her task / information requirements / learning needs. I will show how the conceptual framework can be used for evaluation of current digital libraries interfaces and how can it be used to guide design of new generation of educational digital libraries.Item Whisper: The Role of Digital Libraries(2005-08-09T22:55:21Z) Slater, Mark DavidItem Whisper: Supporting Knowledge Transfer for Academics(2005-08-09T22:49:19Z) Slater, Mark DavidToday, despite decades of research, computer support for academic knowledge workers is fragmented and poorly integrated. While office automation and other forms of Computer Supported Collaborative Work(CSCW) approacheshavebenefitted academics, nosingleenvironmenttodayintegratesthebasic activities of the academic knowledge worker, including: individually or collaboratively writing research papers, sharing researchpapers, reviewingpapersforpublicationin ajournal or conference, andpersis tently sharing comments and observations on existing literature. We have developed an initial model that describes the mechanisms used by academics to transfer knowledge to other individuals, project groups, and communities, as well as mechanisms used to transfer knowledge within project groups and communities. Based on ourmodel, with revisions stemmingfromtheresults of ourstudy,wewilldevelop a novel environment calledWhisper(forWebInformationSharing Project),that will supportthe mech anisms of knowledge transfer between academics. Whisper will provide tools for academics, including digital library spaces with shared articles and annotations, versioned file spaces, archived discussion lists, and communityjournals. By creating an online workspace for academics of all fields, Whisper can reduce the cost and effort needed to setup shared workspaces between physically distant collaborators, as well as interdisciplinary collaborations. The persistent repository of project information, community discussions, and online journals will provide easier access to past and current research; this helps facilitate knowledge transfer long aftertheentitythat created theknowledgeisdefunct orbecomesunavailable. Inaddition,ourmodel willbe abletoidentify: theknowledgetransfer mechanisms most appropriatefor agiven entitypair,the point at which formal communities are viable, and at what point mass knowledge transfer mechanisms are viable within a given community.Item Contextualizing Science Education via Earth System Science Events for Meaningful Lifelong Learning(2005-08-09T22:27:21Z) de la Chica, SebastianItem Contextualizing Science Education via Earth System Science Events for Meaningful Lifelong Learning(2005-08-09T22:18:19Z) de la Chica, SebastianThe widespread deployment of ubiquitous communication technologies, including growing Internet access, in the early 21st century has resulted in a growing number of information sources available for educational purposes. These online information sources contribute to an educational landscape increasingly capable of near real-time access to news coverage, scientific data, and critical analyses about earthquakes, volcanic eruptions, tsunamis, and similar Earth system science (ESS) events. By contrast, traditional science textbooks provide sanctioned quality educational content, but require content updating cycles several orders of magnitude longer than online information sources. Lacking meaningful context, scientific information in traditional textbooks often leads to disconnected rote learning and limited understanding of scientific concepts. Lacking the appropriate cognitive skills, learners often fail to recognize and connect the salient scientific concepts and social issues underlying news coverage of significant ESS events with their existing scientific knowledge. Nationally-recognized science education standards have addressed the importance of learning how to be a scientist through learning goals related to science inquiry and critical thinking skills in authentic settings, including topics derived from current events (National Research Council, 1996; Project 2061, 1993). While real-world ESS events may support authentic integration of science in the classroom with science in the world, learners require appropriate cognitive skills to adequately process and integrate scientific content from diverse sources in the context of their immediate science curriculum learning goals. The proposed research addresses the following research questions: • How does the introduction of real-world Earth system science events change learners’ existing scientific understandings and their comprehension of the social relevance of the science curriculum content? • What are the cognitive skills and strategies required for meaningful learning from multiple sources in an online science research environment? • How can concept maps be integrated with educational digital libraries to scaffold the development of these cognitive skills and strategies in an online science research environment?Item Digital Libraries & Desktops: How Users View & Use Digital Libraries in Relation to their Own Private Collections(2005-08-08T22:44:42Z) Finneran, ChristinaThis dissertation will study the interaction between frequent users and the digital libraries they regularly visit, specifically to gain a greater understanding of the factors which underly users’ decision-making with regard to the storage of digital library items in their private information collections. An important component of this will be the development of meaningful insights into prevailing user perceptions of the digital library collection within the user work space, and how such perceptions influence and govern the treatment of the items found within the digital library. This dissertation will contribute to the advancement of our understanding of user perceptions and utilization of digital libraries, especially as such relate to their own personal collections. The knowledge generated by this dissertation will help to shape and influence the development of more effective and more responsive digital library design in the years ahead.Item Digital Libraries & Desktops: How Users View & Use Digital Libraries in Relation to their Own Private Collections(2005-08-08T22:29:16Z) Finneran, ChristinaItem Digital Libraries & Desktops: How Users View & Use Digital Libraries in Relation to their Own Private Collections(2005-08-08T22:15:47Z) Finneran, ChristinaThis dissertation will study the interaction between frequent users and the digital libraries they regularly visit, specifically to gain a greater understanding of the factors which underly users’ decision-making with regard to the storage of digital library items in their private information collections.

We survey a representative set of P2P systems in order to build prospective platform and discuss why a super-peer (peer community) based topology is suitable for schema-based P2P applications. Furthermore, we exploit ontologies for storing metadata records in a structured and formal way, and for broadening queries with closely related terms, thus yielding more relevant results. All metadata records into RDF format and a RDF database, such as Sesame, is adopted to store and query these records and schema information. Additionally, since words generally have more than one sense, we have to choose the right sense and highly related terms for extending the query. Such information can be delivered by applying a lexical database, like WordNet, which models terms with their meanings and relationships in between. The resulting prototype system is expected to serve as a framework for re-processing metadata records into structured and semantic-enriched collection in specific domains, as a platform for the searching over heterogeneous collections, and as a source of inspiration for exploiting ontologies in information searching.Item Note to Self: You Must Remember This - LESS BOW!!!(2005-07-25T22:37:45Z) Winget, MeganItem Digital Preservation of New Media Art Through Exploration of Established Symbolic Representation Systems(2005-07-20T22:29:48Z) Winget, MeganIn this paper, I describe my thesis research, which is concerned with digital preservation of new media art. This paper is divided into three sections: the first places technical digital preservation approaches within the context of artistic concerns; the second places digital variable media art within the context of other, more traditional variable art forms; and the third section describes my thesis project and methodology, which is an attempt to define the important characteristics of an existing art form (namely, music) through the exploration of users' annotations; and from that data, make some conjectures regarding the important elements of a new media art object.Item Communication and Storage of Data for Personal Libraries(2005-07-20T21:51:10Z) Alvarez-Cavazos, FranciscoPersonal libraries are proposed by investigating design elements that should be considered in the creation of a distributed digital object store for a personal library system.
