Purpose: This study aims to understand the effect of therapies on dual language children with developmental language disorder (DLD) on a range of bilingual language outcomes, compare with second-language-only therapy and determine whether there is any cross-linguistic transfer. Methods: A systematic review of English articles in 10 electronic…

This review explores challenges and barriers to parent-child interaction which leads to language development in the first 3 years of the child's life. Seven databases yielded 1,750 hits, reduced to 49 evidence-based studies, many of which still had methodological imperfections. Evidence was quite strong in relation to socio-economic status,…

Objectives: The purpose of this study is to review the current empirical research regarding the financial effects of participation in Individual Development Account (IDA) programs. Methods: Peer-reviewed outcome studies identified through electronic bibliographic databases and manual searches of article reference lists are reviewed. A total of 1…

Identifies four categories of end users, based on their searching ability and knowledge of their subject area. The role of the librarian or information specialist in assisting each category of users to fully benefit from online full text databases (FTDs) discussed. (30 references. (CLB)

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…

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…

Explores the use of analog optical disks as a practical, cost effective means of building picture databases. Questions that should be asked to determine whether optical disk is a suitable picture storage alternative for a particular application are identified and three implementation issues--imaging, indexing, and integrating--are discussed. (CLB)

A review of the literature indicates that innovations in technology are making it possible for the consumer of information, the end user, to gather his own information online. The information specialist's role is changing from that of a researcher to a trainer and leader in the information gathering process. Reports on end user training indicate…

Reviews developments and products in the information industry that are aimed at the end user and identifies impediments to end user searching that may explain why end user access has not supported these products. Suggestions for overcoming these impediments are offered. (eight references) (CLB)

Discusses development of digital optical discs and considers both positive and negative features of CD-ROM for information services. Topics discussed include microcomputer-based databases; cost effectiveness; online searching by users; new user populations; the status of information specialists; lack of standards; and future possibilities. (Five…

Compares OCLC, WLN, and RLIN in terms of the composition of the databases, indexes and searching, special uses for public services, costs, and documentation. Selected bibliographies of general public service uses and interlibrary loan applications are provided. (CLB)

Detailed profiles and comparisons of European databanks being marketed in the United States include marketing strategies, subject content, number and types of databases offered, cost information, value added services, and more. Users' views of the viability, ease of use, and strengths and weaknesses of European databases are presented. (CLB)

The practical advice for the evaluation of laser/optical data disk materials (e.g., CD-ROM) is based on a review of the relevant literature. An evaluation framework is outlined and collection development tools and sources of published reviews are identified. (34 references) (Author/CLB)

Examines current activities in subject analysis of large bibliographic databases to assist database managers in making cost-effective decisions. Issues addressed include manual indexing aids, automatic indexing, and connecting indexing terms. Several software packages are described, and future research directions are suggested. (58 references)…

The emphasis of this text is that the problems of information retrieval are the intellectual ones of subject analysis and description. These problems are not easily solved by technology alone, although certain inroads are being made by knowledge-based expert systems and other computer aids to indexing. Linguistic approaches are also showing…
