Discussion of the classification of documents from bibliographic databases focuses on a method of vectorizing reference documents from LISA (Library and Information Science Abstracts) which permits their topological organization using Kohonen's algorithm. Analyzes possibilities of this type of neural network with respect to the development of…

In this paper, we reconsider the merits of unfolding solutions based on loss functions involving a normalization on the variance per subject. In the literature, solutions based on Stress-2 are often diagnosed to be degenerate in the majority of cases. Here, the focus lies on two frequently occurring types of degeneracies. The first type typically…

The author, as a library media specialist, admitted that she needed more study on library organization despite three years of teaching Dewey to her elementary students. To be more accurate, she realized she needed a clearer understanding of what Mr. Melvil Dewey had in mind when he devised his plan for organizing books and information in the…

Edward Frankland and Norman Lockyer researched upon a gaseous spectra in relation to the physical constitution of the sun and named it as "helium" (from Greek "helios" meaning "sun"). Since Lockyer apparently never formally proposed the name in print, it is not known why he chose to use a metallic end "ium".

In this article, I survey the integrated connectionist/symbolic (ICS) cognitive architecture in which higher cognition must be formally characterized on two levels of description. At the microlevel, parallel distributed processing (PDP) characterizes mental processing; this PDP system has special organization in virtue of which it can be…

The virtual pedagogical space that is a home to ten thousands of English courses in the United States and abroad and is referred to the software application called Blackboard is discussed. The ways in which Blackboard as a socially produced and producing space undermined many of the currently professed goal of English studies is illustrated.

The most effective teaching strategies require higher order thinking, but the most used strategies seem to involve lower order thinking. If a comparison could be made between the cognitive rigor of the content standards that students are to be learning and the cognitive rigor of the actual work students are doing, then these kind of data are…

Propensity score analysis is a relatively recent statistical innovation that is useful in the analysis of data from quasi-experiments. The goal of propensity score analysis is to balance two non-equivalent groups on observed covariates to get more accurate estimates of the effects of a treatment on which the two groups differ. This article…

This issue of "Bilingualism: Language and Cognition" is about convergence, a type of language change that is contact-induced and results in greater similarity between two languages that are in contact with each other. In Backus (forthcoming), I have attempted an overview of contact-induced language change, focusing on causal factors, on mechanisms…

"Analysis", the core of graduate business education is probably one of the least understood and most misrepresented learning activities. Everyone seems to claim that they know it, yet most seem unable to actually define it or practice it. This paper reviews Bloom's taxonomy of learning objectives with a special focus on "analysis." More…

In this year's analysis of the Top 100 minority producers of postbaccalaureate degrees--master's, first professional and doctoral degrees--the people behind "Diverse Online" continues their tradition of celebrating the colleges and universities in the United States that confer the largest number of graduate and professional degrees to students of…

This article examines how academic knowledge and power have shaped the discourse on human classification and how political authorities use academic knowledge producers to legitimize public policy. Specifically, the article draws on the role of John M. MacEachran, a former academic at the University of Alberta, in the implementation of the Alberta…

In this article we describe the emerging area of text classification research focused on the problem of collaborative learning process analysis both from a broad perspective and more specifically in terms of a publicly available tool set called TagHelper tools. Analyzing the variety of pedagogically valuable facets of learners' interactions is a…

In this paper, we present a data-based user modeling framework that uses both unsupervised and supervised classification to build student models for exploratory learning environments. We apply the framework to build student models for two different learning environments and using two different data sources (logged interface and eye-tracking data).…

This book is for community leaders, librarians, library committees, volunteers, aid workers and others who are interested in the practical aspect of starting and maintaining a successful library. Throughout the developing world, countless dedicated people respond to the pressing need for information in their communities by helping to start a…
