Simulations have been implemented globally in nursing education for years with diverse conceptual foundations. The aim of this scoping review is to examine the literature regarding the conceptualizations of learning and pedagogical models in nursing simulations. A scoping review of peer-reviewed articles published between 2000 and 2013 was…

With the advent of the Web, the notion of "information retrieval" has acquired a completely new connotation and currently encompasses several disciplines ranging from traditional forms of text and data retrieval in unstructured and structured repositories to retrieval of static and dynamic information from the contents of the surface and deep Web.…

Discussion of commercial document/information retrieval models focuses on the fact that document retrieval, specifically access to intellectual content, is a complex process which is most strongly influenced by the size of the document collection, the type of search (exhaustive, existence or sample) and the determinacy of document representation.…

Discussion of XML focuses on indexing techniques for XML documents, grouping them into flat-file, semistructured, and structured indexing paradigms. Highlights include searching techniques, including full text search and multistage search; search result presentations; database and information retrieval system integration; XML query languages; and…

Presents a new model for combining multiple sources of evidence in database merging based on logistic regression, and occurring only when ranks are available as a key to be used to merge different ranked lists obtained by various retrieval schemes. Results indicate better retrieval effectiveness than other approaches. (LRW)

Three aspects of training and education for online searching of bibliographic and databases are addressed: (1) the present status--what is being taught, (2) a proposed model--what needs to be taught, and (3) the implementation of the model--who should teach what. The first section shows which organizations (library and information schools,…

Describes a study evaluating the effectiveness of the Information Retrieval, Ltd. (IRL) Life Sciences Collection database in a field where BioSciences Information Service (BIOSIS) claims to offer comprehensive coverage of the international literature. The two databases are described, and the depth of controlled indexing is compared for the two

Examines the processes that occur when a searcher searches for documents in a reference database, and what relationships exist between psychological descriptions of these processes and models from the domain of information retrieval. Highlights include associational psychological modeling; empirical testing; and information science and psychology.…

Discusses end-user searching in Boolean information retrieval systems considers the role of search intermediaries and proposes a model of user preferences that incorporates a user's profile. Highlights include document representation; information queries; document output ranking; calculating user profiles; and selecting documents for a local…

This self-improvement manual developed for experienced online searchers presents and discusses several alternative search strategies and their appropriate use to achieve the desired outcome. The manual is divided into two parts: (1) an eight step model of the total search process emphasizing how the decision of the information professional affects…

Revised to reflect changes in both DIALOG and ERIC, this second edition of a self-improvement manual for online searchers who wish to refine their skills presents three basic approaches to searching and provides illustrations from DIALOG's ERIC ONTAP database. The manual is divided into two parts: an 8-step model of the total search process which…

The Hepatitis Knowledge Base (text of prototype information system) was used for modifying and testing "A Navigator of Natural Language Organized (Textual) Data" (ANNOD), a retrieval system which combines probabilistic, linguistic, and empirical means to rank individual paragraphs of full text for similarity to natural language queries…

Proposes a model of the search term selection process based on an empirical study of professional searchers during the pre-online search stage; the model characterizes the selection of search terms as the navigation of different discourses. Six discourses emerged as sources of search terms: controlled vocabularies; documents and the domain; the…

This paper reports on an application of parallel models to the area of information retrieval and argues that massively parallel, distributed models of computation, called connectionist, or parallel distributed processing (PDP) models, offer a new approach to the representation and manipulation of knowledge. Although this document focuses on…

Two information dissemination centers at University of California at Los Angeles and University of Georgia studied the interactions between computer based search facilities and their users. The study, largely descriptive in nature, investigated the interaction processes between data base users and profile analysis or information specialists in…
