Followed 150 children over four years who were classified according to cluster analysis of teacher ratings into four types of social withdrawal: unsociable, passive-anxious, active-isolate, and sad-depressed. Found that unsociable children had elevated sociometric neglect rates, active-isolates had higher levels of rejection, and sad-depressed had…

An overview is provided of the similarities and distinctions between individuals with autism and those with Asperger syndrome (AS). The cognitive and neurocognitive profiles underlying deficits characteristic of autism spectrum disorders are reviewed and particular emphasis is placed on comparisons of high-functioning autism to AS on the basis of…

This article considers whether Asperger syndrome (AS) should necessarily be viewed as a disability or as a difference. It concludes that "difference" is a more neutral and fair description. A model (the emphasizing-systemizing model) is summarized that attempts to define in what way individuals with AS are different. (Contains references.)…

The second of two linked articles develops two more mapping typologies: first, an approach to the what, why, and how of leaders, leading, and leadership; and second, the presentation of possible positions that knowledge workers can take when they use and produce knowledge about leadership practice. (Contains 10 notes and 73 references.) (MLF)

A study that followed two genetically homogenous cohorts of Finnish children born in 1966 (n=11,965) and 1965-1986 (n=9,432), found there was no change in total incidence of intellectual disability. However, there was a shift from severe and moderate towards mild; whereas profound intellectual disability remained at the same level. (Contains…

Presented is a simple, unified approach to chemical nomenclature which employs the distinction between the terms chemical substance and chemical species. The classification of matter and chemical nomenclature are used as examples to illustrate this scheme. (CW)

Described is an interactive database of chemical information called "KC? Discoverer: Exploring the Periodic Table." An overview of the program and details of specific functions are given. The uses of this program in teaching undergraduate inorganic chemistry are stressed. (CW)

Described are two reviews of a computer software package: "The Periodic Table Stack," a Hypercard stack that operates on a database of information about the properties and reactions of the elements and designed to help users of Macintosh computers access data found on "KC? Discoverer." Discussed are features of the program and…

Suggests ways census data in the "Statistical Abstract of the United States" may be used to develop thinking skills in economics. Presents a lesson in which students collect data on different types of work done by a small group of workers. Emphasizes the process of classifying workers in order to provide experience with this reasoning…

After viewing a videotaped continuing education program on communication skills, 51 pharmacists' cognitive gains were compared with those of a control group of 34 pharmacists. Although a significant difference appeared between experimental and control groups, the experimental group's scores remained low by state licensing standards. (Author/MSE)

Describes a project that examined the effects of incorporating subject terms from the Dewey Decimal Classification (DDC) into a bibliographic database. It is concluded that the incorporation of DDC and possibly other library classifications into online catalogs can enhance subject access and provide additional subject searching strategies. (11…

Discussed is an extension of the conventional method for studying the organometallic chemistry of transition metals that may be useful to show how the various existing types of low-valence complexes can be constructed. This method allows students to design new types of complexes that may still be nonexistent. (CW)

An overview of contemporary Hispanic dialectology, focusing on phonological phenomena, syntax, classification schemes, and bilingual communities, demonstrates that dialectology has long ceased to be the collection of innumerable surface deviations. It is suggested that dialectology is a theoretical discipline searching for universal principles to…

Exploration of major causes underlying the growing amount of classified national security information examines both recent and perennial tendencies. The consequences of this growth for public access, constitutional checks and balances, and changes in the classification system and product are assessed, and corrective measures available to Congress…

Describes the development and outcome of a cooperative computerization effort involving nine public and university museums. The discussion covers the project goals, data development and analysis, and contributions resulting form the project. Appendices provide the system data fields used and a comparison between automation of library and museum…
