The development in information science has enabled an explosive growth of data, which attracts more and more researchers to engage in the field of big data analytics. Noticeably, in many real-world applications, large amounts of data are imbalanced data since the events of interests occur infrequently. Classification of imbalanced data is an…

The purpose of this mixed methods study is to determine the effectiveness of case-based pedagogy in teaching basic principles of information ethics and ethical decision making. Study reports results of pre- and post-assessment completed by 49 library and information science (LIS) graduate students at a Midwestern university. Using Creswell's…

If college science instructors are to use inquiry practices more in the classroom, they need both professional support to foster comfort with the pedagogy and practical ways to engage students in inquiry. Over a semester, we studied 13 community college biology instructors as they adopted bioinformatics problem-based learning (PBL) modules in…

Group decision making is essential in organizations. Group Support Systems (GSS) can aide groups in making decisions by providing tools and process support. GSS is especially useful for geographically or temporally distributed groups. Researchers of GSS have pointed out that convergence processes are hard to accomplish in GSS. Voting tools in GSS…

Presents the concept of the average decision maker as a statistical entity with 10 essential properties, and defines the information state in terms of the decision maker's probability of choice of various courses of action. The implications for a generalized theory of information science are suggested. (33 references) (EAM)

A generalized framework for developing analytical and conceptual relationships involving the flow of information has previously been suggested. This paper provides further refinement, rigor, and extension for some of the earlier relationships suggested. (12 references) (Author)

This paper describes research being carried out at the Ohio State University leading toward a general theory of information flow and analysis. The objectives of this program sponsored by the National Science Foundation include the following: (1) to develop a theory of information flow and analysis; (2) to identify important parameters and…

This research study is based on an application of concepts derived from the Yovits-Ernst Model for a generalized information system. These concepts and their implications are applied to a management decision model for a hypothetical production control problem. The purpose of this investigation is to demonstrate that the theory of the Yovits-Ernst…

In the policy making process, one of the important steps is the consideration of the consequences deriving from the alternative choices. For the case of information policy, the present research has begun the development of a methodology for doing so. The methodology chosen was modeling. Information policy modeling serves the dual purposes of…

This paper deals with the organization of two important areas which interact strongly: information science and decision-making. Both are commonly and extensively used in a variety of ways and share an equally commonly and extensively used variety of definitions. This paper deals with the mutual interaction between information science and…

A generalized framework for developing analytical and conceptual relationships involving the flow of information has been suggested. This paper provides further refinement, rigor, and extension for some of the earlier relationships suggested. In particular, a measure of the amount of information is defined as the difference of the value of the…

Describes the economic and societal perspectives of information and its importance to society by analyzing the nature of the information sector. A new classification model of the information economy is proposed, and implications for policy decision making in an information society are suggested. (25 references) (LRW)

Discusses the concept of cognitive style and its usefulness as a means of analyzing problem-solving or decision-making behavior. Cognitive style dimensions and models useful for analyzing information/library science professionals are described, and the implications of this research for professional training are discussed. There are 13 references.…

Explores ethical issues for online searchers that are exacerbated by the searcher's gatekeeper function--searcher competence, searcher bias, inaccurate search results, misuse of search results by client, and privacy and confidentiality. A model for ethical decision making is presented and a list of guidelines for ethical conduct is suggested. (EJS)

Describes various methods of measuring information contained in a database or in a document collection. Economic worth or utility of information to the user is discussed, the value of data in decision making is considered, and an example comparing information in two library collections is presented.
