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)

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.…

This study examines whether two frequently reported causes of dyslexia, phonological processing problems and verbal memory impairments, represent a double-deficit or whether they are two expressions of the same deficit. Two-hundred-and-sixty-seven Dutch children aged 10-14 with dyslexia completed a list-learning task and several phonological…

The purpose of this study was to find new evidence for phonological coding in written word recognition among deaf Dutch children. A lexical decision task was presented to 48 severely and profoundly deaf children aged from 6 years 8 months to 13 years 5 months, and a control group of Grade 1 hearing children matched on written word recognition.…

We examined the contribution of semantic similarity to morphological priming effects, using the immediate (Exp. 1 and 3) and the delayed variant (Exp. 2) of picture-word interference. Distractor words were either compounds morphologically related to the picture name, but differing with respect to their semantic transparency (hummingbird, jailbird…

This article reports on a research project that explored the manner in which veteran school principals become aware of, and committed to, new perspectives and practices. Personal stories of formative and transformative change from the careers of 23 school principals were collected and analyzed comparatively. Four analytic tools were devised that…

The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

These proceedings contain the papers of the International Conference e-Learning 2015, which was organised by the International Association for Development of the Information and Society and is part of the Multi Conference on Computer Science and Information Systems (Las Palmas de Gran Canaria, Spain, July 21-24, 2015). The e-Learning 2015…

This exploratory-descriptive research focuses on whether children can connect school-based experiences to future jobs that interest them. A cross-national sample of 497 South African and 365 Australian upper primary school children participated in the study. The data from one item of the Revised Career Awareness Survey were analysed using…

This study systematically analyzed social and cognitive processes that underlie the development of argumentative knowledge. Group discussions of controversial issues and explicit instruction in argumentation were expected to help students acquire a sense of the overall structure of an argument, or an argument schema. In a quasi-experiment, 128…
