Investigated the construct validity of Crites' model of career maturity and the Career Maturity Inventory (CMI). Results from a nationwide sample of adolescents, using hierarchical factor analytic methodology, indicated confirmatory support for the multidimensionality of Crites' model of career maturity, and the construct validity of the CMI as a…

In this study of 547 high school graduates, Alderfer's and Maslow's need hierarchy theories were expressed in Markov chain form and were subjected to empirical test. Both models were disconfirmed. Corroborative multiwave correlational analysis also failed to support the need hierarchy concept. (Author/IRT)

Explains the use of learning-hierarchy analysis in inferring hierarchical structures in expert performance, gives an example of a modified learning-hierarchy analysis of expert performance in teacher planning, and recommends that advice-strategies be derived from hierarchical analyses of expertise to provide instructional guidance to novices. (29…

Effects of the orientation of knowledge maps on learning were studied with 28 undergraduate students who were randomly assigned to study maps presented vertically or horizontally. Performance of high and low vocabulary subjects was evaluated. Low vocabulary subjects who used linear maps performed more poorly than any other group. (SLD)

Presents a document-clustering algorithm that uses a term frequency vector for each document in a Japanese collection to produce a hierarchy in the form of a document classification tree. Introduces an application of this algorithm to a Japanese-to-English translation-aid system. (Author/LRW)

Examines the hierarchy of academic self-concept in four studies. Tests the hypotheses that strong hierarchical relations exist in the academic self-concept structure at a domain-specific level, and that a hierarchy exists in an educational setting with a strong focus on the curriculum. Results reveal support for the multidimensionality of academic…

Attempts to estimate a recursive model of earnings distribution with education, occupation, and hierarchy, using individual data for Japanese males. Proves that hierarchical position is very significant in determining earnings level. Compares the influence of education and earnings distribution in Japan and France. Includes 3 tables and 20…

Aids are given to help the librarian recognize vertical and horizontal communication, and to expedite horizontal interaction with the patron that exhibits vertical tendencies. (Author)

Explores why higher education no longer needs complicated hierarchies in faculty titles, and proposes the elimination of the distinction between associated and full professor. (EV)

This paper criticizes the Yeany, Yap, and Padilla paper (1986). Questions the internal consistency about hierarchical relationships of integrated processes and cognitive reasoning concerning procedures used for the generation of subhierarchies, instrumentation used to assess the process skills, and rigor of lexicon. (YP)

Describes and examines the taxonomic linguistic system, a multi-level classification of language. Notes that this system not only formed the basis for all reading instruction, but also influenced reading research. Argues that this system should be replaced by one less simplistic and more realistic. (MM)

The major facts of motion perception are summarized, and three major problems regarding motion perception for moving objects, stable environments, and locomotion in a stable environment are elaborated. A hierarchy of motion types is presented. Evidence that the stimulus for motion is relational is considered. (SLD)

Three experiments examine how preschoolers partition their basic level categories to form subordinate level categories and whether these have inductive potential. Results suggest that contrastive information promotes the emergence of subordinate categories as a basis of inductive inference and newly established subordinate categories can retain…

This article argues that many Conservative and Labour backbenchers have reacted to the Downing Street spin on the 2005 Education White Paper rather than to the White Paper itself. But it is acknowledged that an increase in the variety of secondary schools can lead to division, discrimination and a disturbing emphasis on hierarchy.
