This volume is part of a set that documents the data collection of the 1990-91 Schools and Staffing Survey (SASS). Volume I provides the essential background information for the survey. This volume is the restricted-use codebook, which contains the variable names and position numbers for all survey and sampling variables. All data variables have…

Explains the development of standardized coding for digital text, especially for multilingual text, that has culminated in the Unicode standard. Topics include the University of Michigan's Humanities Text Initiative (HTI); a history of character sets; transliteration; non-Roman languages; fonts; and barriers to adoption of the Unicode standard. A…

Results of three studies, involving 606 high school and college students, show that the perceived randomness of a sequence is better predicted by its encoding difficulty than its objective randomness. Results imply that judging the extent of randomness of a sequence is based on the attempt to encode it. (SLD)

Cognitive load theory suggests that the manner in which information is presented can interfere with learning. For example, in studying equations with unfamiliar notations, a heavy extraneous cognitive load is generated because mental integration of notations and meanings is required. Discusses four experiments with high school students designed to…

Explains how to improve visual displays employed in school finance by examining a theoretical framework and applying it to the displays. Discusses and illustrates important display principles based on William Cleveland's ideas about decoding/encoding, length judgments, distance, detection, and superimposed curves; and Edward Tufte's work on data…

Presents an approach to automatic matching and linkage of citations between databases which applied 14 coding techniques and measured their effectiveness in terms of efficiency of retrieval of duplicates with minimal false hits, reliability, and performance. (EAM)

Discusses origins of Transborder Data Flows (TDFs) as an international problem in the early 1970s. Shows how technological development in telecommunications and networks has made regulation more complex and urgent. Recommends the internationalization of the Key Escrowed Encryption System (KEES) and the development of broad international TDF…

Results from a study involving 34 undergraduates supported the prediction from Paivo's dual coding theory (1986) that imaginal elaborations during lectures assist students' recall of both episodic and declarative information. The prediction that episodic memories would mediate retention of declarative information from the lecture was not…

Discusses the integration of Standard General Markup Language, Hypertext Markup Language, and MARC format to parse classified analytical bibliographies. Use of the resulting electronic knowledge constructs in local library systems as maps of a specified subset of resources is discussed, and an example is included. (LRW)

Results of two experiments involving 206 upper elementary school students supported the hypothesis that less-skilled readers suffer working memory deficits that contribute to comprehension problems independent of their problems in phonological coding. Results also suggest that constraints in an executive system may contribute to reading…

Describes the Text Encoding Initiative (TEI) project and the TEI header, which documents electronic text in a standard interchange format understandable to both librarian catalogers and nonlibrarian text encoders. The form and function of the TEI header is introduced, and its relationship to the MARC record is explained. (10 references) (KRN)

Describes a method for coding themes directly from audiotapes without transcription and issues and methods by which reliability can be established. A study of concerns of professionals being trained on 11 school-based support teams coded by 2 raters and based on 19 hours of audiotaped interviews illustrates the method. (SLD)

Examination of two-letter high-point code frequency tables of four Self-Directed Search samples and Holland's translation of occupational titles verified the fit of the circumplex model, supporting Holland's person-environment hypothesis. (SK)

Functional relations underlying map-passage learning were studied through the effects of structural hierarchy on recall for 80 undergraduates. Recall for passage content was greatest when content was at the top of the map and passage structures. Implications for instruction are discussed. (SLD)

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)
