Proposes an object-oriented conceptual data model tailored for organizing and representing basic map elements and their relationships, as well as operations of interest for the management of geographic data. Discussion includes both conceptual abstraction primitives (classification, generalization, and aggregation) and a spatial abstraction…

This study of 65 children (ages 10-13) with dyslexia found no discrete subgroups. Variability in performance on reading tasks was quite similar for the dyslexic and reading age-control groups. A few children with dyslexia resembled phonological dyslexics and surface dyslexics, but these subjects were still part of a continuum. (Author/JDD)

The matching-to-sample performances of three young adults with autism and four children (ages four to nine) without intellectual disabilities were examined in three experiments using complex sample stimuli. Results for all subjects showed that each of two redundant relevant sample elements and their respective comparison stimuli were substitutable…

A series of experiments revealed that noun-category bias in children's word learning is present as early as two years of age. Findings indicate that, when children interpret the meaning of novel nouns, they do not sample randomly from the range of possible meanings but focus instead on category relations. (RH)

The tradition of negotiating indirect costs in grants should be abandoned, and research administrators should instead offer different levels of service depending on what the sponsor wants to spend. Three levels of overhead rate are suggested (super, regular, and economy) and their corresponding levels of service are defined. (MSE)

An asymmetric version of J. Cohen's kappa statistic is presented as an appropriate measure for the agreement between two observers classifying items into nominal categories, when one observer represents the "standard." A numerical example with three categories is provided. (SLD)

The ability of 31- to 36-month-old children to act in accordance with rules was assessed in 2 slightly different experiments using sorting tasks and knowledge tasks. Taken together, the results of both experiments imply a relatively rapid, age-related change culminating in the ability to systematically execute rules that require access to extant…

Argues that librarianship is intimately connected to the structures and thought patterns of bibliographic control and that bibliographic control should be the theme for all practical coursework in library education. A sample syllabus is proposed. (EA)

Outlines three broad approaches to defining the rural and concludes that only the discussion of the rural as locality is adequate. Introduces a theory of social representations of the rural and its relevance to the rural definition debate. (152 references) (KS)

Describes the concept of Information Based Education, provides a theoretical basis for investigating the role of information in education, and begins developing a classification scheme for documenting and distinguishing among information bases. Attributes of information associated with information resources, information skills, information…

Introduces this special issue on the construction of a federal policy-impact code for classifying the nation's rural school districts. Despite the diversity in rural areas, rural education issues are somehow unique. The goal is to adequately reflect the impact of government education policies upon rural schooling. (KS)

Argues that a new typology, based on the five modes of composition commonly used in rhetorical studies (description, narration, argumentation, exposition, and criticism), provides a more definitive classification scheme for contemporary journalism than the old news/feature/editorial trichotomy. (SR)

Offers a model of the elements and disciplines that contribute to the field of technical communication, and develops from the model a framework for a taxonomy that recognizes differing names for parallel processes. (SR)

Discusses the basic taxonomy of linguists, that is the differences between formalist and functionalist approaches, as suggested in a previous article, focusing on the implications of such a taxonomy. (JL)

It is proposed that there is a modular but interconnected system underlying the perceived hierarchical organization of objects. The discussion centers on neural and cognitive mechanisms of organizing objects within objects in at least four separate subsystems. (SLD)
