The aim of this study is to examine Finnish students' school engagement profiles in the light of the data collected in the PISA (Programme for International Student Assessment) in 2003. Even though Finnish students' cognitive achievement has proved excellent in various international assessments, their school engagement has not been flattering. The…

Recently, there has been an increasing level of interest in reporting subscores. This paper examines the issue of reporting subscores at an aggregate level, especially at the level of institutions that the examinees belong to. A series of statistical analyses is suggested to determine when subscores at the institutional level have any added value…

This paper clusters and ranks the research performance of 36 Australian universities according to their research performance over the period of 1998-2002. Research performance is measured according to audited numbers of Ph.D. completions and publications, and research grants income (in accordance with rules established by the Department of…

This study examined two conceptions of perfectionism in relation to interpersonal problems. Two hundred and seventy-nine undergraduate participants completed the Almost Perfect Scale-Revised (APS-R) and the Dyadic Almost Perfect Scale (DAPS). The authors used empirically derived discriminant functions (APS-R) and cluster analysis (DAPS) to…

Broad-based empirical outcomes assessment is an increasingly evident part of governmental services and this trend is particularly apparent in education. The clearest manifestation of this trend in education has been the advent of high-stakes broad-based testing and accountability programs in K-12 education. Although this assessment regime has not…

The purposes of this study were to: (a) examine the differences within 11 specific kinematic variables and an outcome measure (ball velocity) associated with component developmental levels of humerus and forearm action (Roberton & Halverson, 1984), and (b) if the differences in kinematic variables were significantly associated with the differences…

This study investigated the validity of a statewide alternate assessment program, IASEP (Indiana Assessment System of Educational Proficiencies) by examining supporting profile patterns on the 100 core IASEP items of individuals with significant disabilities. Participants were 5,192 students ranging in age from 7-21 years with special education…

The modular exponentiation, y[equivalent to]x[superscript k](mod n) with x,y,k,n integers and n [greater than] 1; is the most fundamental operation in RSA and ElGamal public-key cryptographic systems. Thus the efficiency of RSA and ElGamal depends entirely on the efficiency of the modular exponentiation. The same situation arises also in elliptic…

This study identifies the variables in construction of concept maps and purposefully tests the instructional effects of concept mapping in facilitating student achievement when those identified variables are manipulated. Concept map development consists of three important elements: the concepts, propositions and its hierarchical structure. A total…

Three important methods areas of multivariate analysis that are not always thought of in terms of latent variable constructs, but for which latent variable modeling can be used to great advantage, are discussed. These methods are: (1) random coefficients describing individual differences in growth; (2) unobserved variables corresponding to missing…

This paper focuses on three aspects related to the conceptualization and application of canonical correlation analysis as a dominant statistical model: (1) partial canonical correlation analysis and its application in statistical testing; (2) the relation between canonical correlation analysis and discriminant analysis; and (3) the relation…

The present paper suggests that multivariate techniques are very important in social science research, and that canonical correlation analysis may be particularly useful. The logic of canonical analysis is explained and discussed. The necessity of using replicability/generalizability analyses is argued. It is suggested that cross-validation…

A comparative survey of 46 Alaska school superintendents and 520 in the nation at large reveals that nearly all the superintendents in both groups consider their relationship with the school board to be important and spend a considerable amount of time on that relationship. A positive correlation emerges between the importance superintendents…

A study examined public perceptions of unethical employee acts as a function of variations in a corporation's cultural image, with emphasis upon the effect of congruent and incongruent organizational messages upon the perception of the degree of unethicality. Subjects, 200 adults approached at public locations, were asked to: (1) read one of three…

Three alternative solutions available for analysis of variance (ANOVA) using two-way and three-way completely randomized factorial designs with disproportional cell sizes across all two-way and three-way summary tables with no empty cells are discussed. These solutions are categorized as unique, sequential, and experimental. The procedures used,…
