Conceptual modeling of databases is a complex cognitive activity, particularly for novice database designers. The current research empirically tests a new pedagogy for this activity. It examines an instructional approach that stresses visualizing gradual transitions between levels of abstraction in different hierarchic levels of a relational…

Purpose: Most educational assessments tend to be constructed in a close-ended format, which is easier to score consistently and more affordable. However, recent work has leveraged computation text methods from the information sciences to make open-ended measurement more effective and reliable for older students. This study asks whether such text…

The term data scientist has only been in common use since 2008, but in 2016 it is considered one of the top careers in the United States. The purpose of this paper is to explore the growth of data science content areas such as analytics, business intelligence, and big data in AACSB Information Systems (IS) programs between 2011 and 2016. A…

Background: The U.S. health care system has been under immense scrutiny for ever-increasing costs and poor health outcomes for its patients. Comparative Effectiveness Research (CER) has emerged as a generally accepted practice by providers, policy makers, and scientists as an approach to identify the most clinical- and cost-effective interventions…

The Federal Government is introducing a new funding model for research in Australian higher education institutions, the Research Quality Framework (RQF). This paper provides an overview of the RQF and looks at possible impacts of the RQF on academic libraries in Australia. These impacts are drawn from experience at one Australian university,…

Introduction: The perceived information needs of teachers who specialize in reading instruction for at-risk first graders were studied and related to frameworks for the role of social context in information needs, seeking and use. The frameworks considered were: disciplinarity, role theory in work settings, small worlds and information grounds and…

There are described methods used to minimize data files dimension. There are defined indicators for measuring size of files and databases. The storage optimization process is based on selecting from a multitude of data storage models the one that satisfies the propose problem objective, maximization or minimization of the optimum criterion that is…

Presents abstracts of 15 special interest group (SIG) sessions. Topics include navigation and information utilization in the Internet, natural language processing, automatic indexing, image indexing, classification, users' models of database searching, online public access catalogs, education for information professions, information services,…

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.…

Defines information tectonics as the organizing of information in structures and good information tectonics as being adapted to the needs of the user. Topics discussed include the influence of electronic information technology and electronic databases; hypertext; hierarchical information structures; cross-graining, e.g., the Dewey Decimal system;…

A new theory of sign structure is proposed which explains the syntactic, semantic and pragmatic classification of signs. The theory comprises in part a language capable of relating studies of information processes across a range of disciplines, including communication science psychology, computer science, and linguistics. The power and utility of…

This report examines a series of general models that represent the process of merging records from separate files when it becomes essential to inhibit identifiability of records in at least one of the files. Models are illustrated symbolically by flow diagrams, and examples of each variation are taken from the social sciences. These variations…

Proposes a new learning algorithm to improve the retrieval effectiveness of the search system used in the hypertext environment using an extended Boolean model with links to improve the ranking of retrieved items. Highlights include the basic retrieval scheme, the learning scheme, and a review of basic probabilistic retrieval models. (Contains 32…

Educational dissemination has contributed a number of innovative concepts and strategies to information science. Much-misunderstood ERIC, which combines research reports with policy documents and teaching materials, is one of the first and best examples of a field-oriented rather than discipline-oriented database. Building on ERIC, federal…

The findings, recommendations, and conclusions of a policy-oriented, multi-disciplinary study of copyright in computer-readable works are reported. The foundations of copyright are examined for basic principles, and the theory of public goods is applied to develop the rationale for copyright protection. The judicial history of copyright in the…
