Several hierarchical classes models can be considered for the modeling of three-way three-mode binary data, including the INDCLAS model (Leenen, Van Mechelen, De Boeck, and Rosenberg, 1999), the Tucker3-HICLAS model (Ceulemans,VanMechelen, and Leenen, 2003), the Tucker2-HICLAS model (Ceulemans and Van Mechelen, 2004), and the Tucker1-HICLAS model…

A central question in psycholinguistic research is how listeners isolate words from connected speech despite the paucity of clear word-boundary cues in the signal. A large body of empirical evidence indicates that word segmentation is promoted by both lexical (knowledge-derived) and sublexical (signal-derived) cues. However, an account of how…

Article 12 of the United Nations Convention on the Rights of the Child holds that young people have a right to participate in matters affecting them. While all members of the United Nations have ratified the Convention (with the exception of the United States and Somalia), there are numerous challenges associated with implementing the…

The higher education literature suggests that alternative leadership styles are replacing the traditionally held definitions of leadership and provide new and different (and possibly superior) ways to understand leadership. This article looks for parallels within the current leadership literature to see if community college administrators use the…

This paper presents concepts and principles pertinent to the development of cross-level and multilevel theory in organizational science by addressing a number of fundamental theoretical issues. It describes hierarchy theory, systems theory, and mixed-level models of organization developed by organizational scientists. Hierarchy theory derives from…

Intended to facilitate the preparation of thesauri for the indexing of documents in any subject field, this report presents a set of rules pertaining to the complex issues and questions involved in indexing vocabulary development and construction. After a brief discussion of the nature, functions, and components of indexing vocabularies, a set of…

A review of some of the basic approaches to the study of supervision in organizations leads to the conclusion that the behavioristic methodology of searching for temporal and spatial correlations between assessed events without establishing specific connections to theoretical networks has provided an inadequate basis for the understanding of the…

This position paper details the AFT's opposition to vertical staffing patterns which create salary differentials based on different "levels" of responsibility and thus foster disunity among teachers. It supports, rather, the concept of horizontally differentiated roles and responsibilities, which bases extra salaries upon the union principle of…

A Monte Carlo study was made of the recovery of cluster structure in binary data by five hierarchical techniques, with a view to finding which data structure factors influenced recovery and to determining differences between clustering methods with respect to these factors. (LMO)

A nontechnical exposition of graph theory is presented, followed by survey of the literature on applications of graph theory in research in education and related disciplines. Applications include order-theoretic studies of the dimensionality of data sets, the investigation of hierarchical structures in various domains, and cluster analysis.…

This study examined the relationship among principals' behavior in administering regulations, their hierarchical influence, and teacher loyalty to principals. A significant relationship was found between rule behavior of secondary principals and teacher loyalty, and hierarchical influence was significantly related to teacher loyalty for both…

A sequence for teaching quadratic equations is presented. Considered are: multiplying arithmetic binomials, multiplying algebraic polynomials, reversing the process, missing terms, perfect squares, other special forms and diagrams, quadratic equations, completing the square, systematizing the process, the general form, graphing equations, and…

Describes the construction (input preparation, computer processing, and presentation) of Classaurus, a vocabulary control tool used for indexing according to the Postulate-based Permuted Subject Indexing (POPSI) language. The efficiency of an online classaurus with facilities for direct accessing and updating is discussed. (MBR)

Discusses the educational system in Germany, focusing on science education in the academically oriented Gymnasium. Typical curricular patterns and instructional strategies are included. Also includes a chart comparing the routing of students through American and German school systems. (JN)

Needs assessment has been regarded as a critical stage in the curriculum development process. However, theoretical efforts aiming at proper formulation of this stage are disappointingly rare in the curriculum literature. This article is based on the recognition of this fact and proposes a multilevel conception of needs assessment in the curriculum…
