Leadership is critically important because it affects the health of the organization. Research has found that leadership is one of the most significant contributors to organizational performance. Expanding and replicating previous research, and focusing on the specific telecommunications sector, this study used multiple correlation and regression…

The authors examined the subtype structure of smokers classified in the precontemplation stage of change within the transtheoretical model. From a general practice-based sample of 1,499 daily smoking patients from Germany (participation rate 80%), they used a subgroup of 929 smokers who were classified in the precontemplation stage and applied…

The dependent variable in a regular linear regression is a numerical variable, and in a logistic regression it is a binary or categorical variable. In these models the dependent variable has varying values. However, there are problems yielding an identity output of a constant value which can also be modelled in a linear or logistic regression with…

The problem of modeling information systems is studied with a focus on predictability. Syntactic, semantic, and pragmatic criteria are discussed, and 11 references are cited. (Author/BK)

A connectionist model, SEarch via Recursive Rejection (SERR), is presented that performs across a window defining the model's functional field. Implications are discussed, and results of 5 experiments involving 19 male and 19 female adults and adolescents that test novel predictions derived from the model are presented. (SLD)

In textbooks, foreign (second) language reading proficiency is often evaluated through comprehension questions. In case, authentic texts are used as reading material, such questions should be prepared by teachers. However, preparing appropriate questions may be a very demanding task for teachers. This paper introduces a method for automatically…

An empirical model was developed to represent the organization of the value-attitude system as postualted by Rokeach, and the model was used to determine the internal consistency of the system, its structure and components, and the extent to which the system permitted the prediction of attitudes from values.

A rudimentary description of Markov Chains is presented in order to introduce its use to describe and to predict authors' movements among subareas of the discipline of ethnomusicology. Other possible applications are suggested. (Author)

Paper presents derivations of expressions for functions for any absorbing Markov-chain model. (Author)

The hypothesis that structured representations can be compared via structural alignment and the prediction that similarity comparisons lead subjects to attend to the matching relational structure of a pair of items were supported through 4 experiments involving 218 undergraduates. Results indicate that similarity involves alignment of structured…

The generalizability of the affective process models of J. M. Gottman et al. (1998) was examined using a community-based sample of 85 married or cohabiting couples with at-risk backgrounds. Predictive associations between affective processes assessed at about age 21 years and relationship status and satisfaction assessed approximately 2.5 years…

The project summarized by this report involved a preliminary design of a model for estimating and predicting the quantity and composition of solid waste and a determination of its feasibility. The novelty of the prediction model is that it estimates and predicts on the basis of knowledge of materials and quantities before they become a part of the…

This study assessed the predictive utility of a classification-based model versus a representational memory-based model to account for the effects of verbal training on the acquired equivalence and distinctiveness paradigms. (Author/JMB)

A number of statistical procedures that were developed in 1983 at the University of Medicine and Dentistry of New Jersey-Rutgers Medical School to verify the suspicion that a student cheated during an examination are described. (MLW)

Studies of organizational characteristics and their relationships to managerial judgments of overall effectiveness of subordinate organizational units are reviewed and evaluated. (MK)
