Many states and school districts are rethinking how they do educational assessment. A few are going further: attempting to build "balanced," "comprehensive," or "next-generation" assessment systems. At the same time, practitioners and researchers have long mulled the purposes and parts such systems should have. But…

This dissertation introduces a theory of information quality to explain macroscopic behavior observed in the systems engineering process. The theory extends principles of Shannon's mathematical theory of communication [1948] and statistical mechanics to information development processes concerned with the flow, transformation, and meaning of…

This thesis deals with "large-scale" detection problems that arise in many real world applications such as sensor networks, mapping with mobile robots and group testing for biological screening and drug discovery. These are problems where the values of a large number of inputs need to be inferred from noisy observations and where the…

Uninterrupted, high-bandwidth network connectivity is crucial for higher education. Colleges and universities increasingly adopt gigabit wireless solutions because of their fiber-equivalent performance, quick implementation, and significant return on investment. For just those reasons, Rush University Medical Center switched from free space optics…

This report describes the principal findings and recommendations of a 2-year Rand research project on machine-aided knowledge acquisition and discusses the transfer of expertise from humans to machines, as well as the functions of planning, debugging, knowledge refinement, and autonomous machine learning. The relative advantages of humans and…

Describes a methodology for management information systems design that employs a formalized framework for significantly involving manager-users in the design process. A key element of the methodology is the development of descriptive and normative system models based on the concept of a "linear responsibility chart." (Author/JG)

A history of educators' concern with systematic production and utilization of educational knowledge (KPU) since the beginning of the century is presented. The influence of Paul Mort on the KPU tradition from the 1930's to the 1960's, and of Federal policies on educational research and dissemination since the 1960's is investigated. (Author/MJB)

A workshop focused on major research issues in networking and communications. This report defines the context for research priorities and initiatives and deals with issues in networking and communications. Fifteen major research priorities and four research specific initiatives were identified by participants as areas that should be pursued over…

For the past 15 years there has been a serious interest in the processing of natural language (English) by researchers in Artificial Intelligence (A.I.). This processing has included machine translation, question-answering systems, man-machine dialogue, and speech understanding. This interest has engendered an awareness of and a concern with the…

Organizational communication includes all verbal and nonverbal stimuli affecting individual behavior and can be defined in terms of purpose, operational procedures, and structural elements. The fundamental element is the organization unit. Related to this unit are three other elements of organizational communication--communication networks,…

Implementation of information systems has lagged in many areas of clinical healthcare for a variety of reasons. Economics, data complexity and resistance are among the often quoted roadblocks. Research suggests that physicians play a major part in the adoption, use and diffusion of information technology (IT) in clinical settings. There are also…

A more unified approach to communication theory can evolve through systems modeling of information theory, communication modes, and mass media operations. Such systematic analysis proposes, as is the case care here, that information models be based upon combinations of energy changes and exchanges and changes in receiver systems. The mass media is…

Presents the opening remarks and keynote addresses of a conference held in Toronto June 1-3, 1988. In the first address W. David Penniman presents a brief history of information technology and discusses issues of current concern. In the second, Jeffrey Katzer questions current assumptions underlying information science and discusses communications…
