Studies of memory impairment in humans and experimental animals have been fundamental to learning about the organization of memory and its cellular and molecular substrates. When memory impairment occurs, especially after perturbations of the nervous system, the question inevitably arises whether the impairment reflects impaired information…

Discusses the distinctive differences between the English and Chinese languages from the system designer's point of view and explores the potential problems for Chinese information retrieval systems, focusing on character entry and retrieval. The advantages and disadvantages of current approaches are discussed, and a regular expression search…

Compares two approaches to document delivery and storage--microform and CD-ROM--in terms of storage capacity, accessibility, production, and cost considerations. Strengths and weaknesses of each medium are noted. It is concluded that libraries should select, integrate, and explore the different features of both technologies. (12 references) (MES)

Argues that a national preservation effort is needed to protect Catholic newspapers. Discusses the American Theological Library Association, the Center for Research Libraries, the Catholic Archives of Texas, the Philadelphia Archdiocesan Historical Research Center, as well as digital preservation efforts and grant possibilities. (AEF)

The question raised here is about the extent that liberal individualism and the consumerist ethos is the result of technology and to what extent is it the cultural norm of modernity. There has been a polarization in the way technology is understood. Predominantly it is assumed to be neutral but it can also be argued that technology exacerbates the…

This report describes approaches to database translation (i.e., transferring data and data definitions from a source, either a database management system (DBMS) or a batch file, to a target DBMS), and recommends a method for representing the data structures of newly-proposed network and relational data models in a form suitable for database…

A plan for a long term tracking system for handicapped children (birth to 5 years old) in Illinois is considered. The plan, based on agreements among five state agencies, could be used in a variety of ways, including for direct client care, statistical recordkeeping, and service evaluation. Advantages of an interactive system are identified, and…

Classifies and briefly describes several types of optical storage media available today--read-only and write-once analog disks, read-only and write-once digital disks and erasable disks. The appropriateness of CD-ROM (compact disk read-only memory) for use in libraries of developing nations is discussed in terms of users' information needs and…

Presents a new image compression algorithm that employs some of the most successful approaches to adaptive lossless compression to perform adaptive online (single pass) vector quantization with variable size codebook entries. Results of tests of the algorithm's effectiveness on standard test images are given. (12 references) (KRN)

Evaluates the performance of different methods of data compression coding in several situations. Huffman's code, arithmetic coding, fixed codes, fast approximations to arithmetic coding, and splay coding are discussed in terms of their speed, memory requirements, and proximity to optimal performance. Recommendations for the best methods of…

Presents two new algorithms for performing arithmetic coding without employing multiplication and discusses their implementation requirements. The first algorithm, suitable for an alphabet of arbitrary size, reduces the worst case excess length to under 0.8%. The second algorithm, suitable only for alphabets of less than 12 symbols, allows even…

Presents an inference algorithm that produces a weighted finite automata (WFA), in particular, the grayness functions of graytone images. Image-data compression results based on the new inference algorithm produces a WFA with a relatively small number of edges. Image-data compression results alone and in combination with wavelets are discussed.…

Examines the need for reevaluating archival principles and practices. Reviews opportunities created to enhance and enrich archival work and difficulties of archiving digital information. Illustrates the consequences in terms of selection and appraisal of records. Emphasizes the impact of digital information on ethical, legal and societal issues.…

Written as an introduction to the concepts of creating a personal or reprint file, this workbook discusses both manual and computerized systems, with emphasis on the preliminary groundwork that needs to be done before starting any filing system. A file assessment worksheet is provided; considerations in developing a personal filing system are…

The evaluation and selection of information/data management system software for the Egyptian National Scientific and Technical (STI) Network are described. An overview of the state-of-the-art of database technology elaborates on the differences between information retrieval and database management systems (DBMS). The desirable characteristics of…
