The study explores whether the naive concepts of "solid" and "liquid" persist in adolescence. Accuracy of responses and reaction times where measured while 41 ninth graders classified different solids (rigid, non-rigid and powders) and different liquids (runny, dense) into solid or liquid. The results show that these naive conceptions affect…

Three experiments explored the significance of deontic properties (involving rights and obligations) in representations of social categories. Preschool-aged children (M = 4.8), young school-aged children (M = 8.2), and adults judged the centrality of behavioral, psychological, and deontic properties for both familiar (Experiments 1 and 2, Ns = 50…

No Child Left Behind (NCLB) performance mandates, embedded within state accountability systems, focus school AYP (adequate yearly progress) compliance squarely on the percentage of students at or above proficient. The singular importance of this quantity for decision-making purposes has initiated extensive research into percent proficient as a…

Anxiety sensitivity has been implicated as a risk factor for the development and maintenance of panic and other anxiety disorders. Although researchers have generally assumed that anxiety sensitivity is a dimensional, rather than categorical, variable, recent taxometric research has raised questions concerning the accuracy of this assumption. The…

Objective: Assess how 8- to 13-year-old children categorized and labeled food items for possible use as part of a food search strategy in a computerized 24-hour dietary recall. Design: A set of 62 cards with pictures and names of food items from 18 professionally defined food groups was sorted by each child into piles of similar food items.…

Directed toward the eradication of sexual and racial bias in bibliographic systems, the subcommittee reports its progress in the identification of areas of classification systems and subject headings requiring change. A policy statement and six guidelines establish a framework for three categories of projects: (1) the need for changes in Library…

Four classification schemes for subject access to children's books are compared. Two of these are general schemes (the "Dewey Decimal Classification" and the abridged "Dewey Decimal Classification"), and two others were devised specifically for children's books (the Toronto Public Library's "Boys and Girls Book Classification" and the Inglewood…

America's colleges and universities have long been the envy of the world. But it would be hard to think of a time when the public has viewed American higher education with greater skepticism. It is a tragedy that colleges and universities are increasingly characterized by their high costs, not their high standards. This fifth edition of…

Suggests guidelines for the classification of law materials in a small library using the published parts of the scheme and some extrapolations from them. (Author)

An investigation was made of the Universal Decimal Classification (UDC) as an indexing language for computer retrieval. Problem areas were identified (notation, schedules, application), new developments reviewed (combining precedence devices, subject analysis matrices, guidelines for schedule revision, pilot schedules, parenthesis-free notation…

A summary of use of DDC in U.S. and Canadian libraries shows that 85 percent of all libraries use DDC; of these, 75 percent use the most recent full or abridged edition. Divisions needing revision are listed and discussed. Librarians want continuous revision but they do not want numerical designation meanings changed. (Author/MBR)

The FID Central Classification Committee is responsible for UDC and its revision. The Standard Reference Code (SRC) has been developed to meet the FID need for a new superstructure of UDC and the UNISIST need for a Broad System of Ordering. UDC and SRC will have a strong influence on each other. (Author/JB)

The tenth abridged edition (1971) of the Dewey Decimal Classification represents, in addition to the updating of the system, many structural improvements which render the system a more workable one, especially for children's room and school library collections. (2 references) (Author)

Mechanization has been introduced in the preparation of UDC and alphabetical indexes using a KWIC Program to access directly documentation files. A special feature of the system is that the KWIC serial number equals the program sorting number equals the encoded UDC form equals the storage or shelving number. (9 references) (Author/NH)

Inconsistencies in the Library of Congress classification schedules relating to Eastern Europe, and ways to improve the system are discussed. (4 references) (SJ)
