Item Applied Multivariate Research, v.12 no.2 (complete version)(Wichita State University, Department of Psychology, 2006)Item From the Editor's desk(Wichita State University, Department of Psychology, 2006) Jackson, Dennis L.Item Subtypes of WIAT performance in a heterogeneous neuropsychological sample(Wichita State University, Department of Psychology, 2006) Saunders, Cory D.; Strang, John D.; Jones, David A.; Goertzen, Larissa R.Patterns of performance on the Wechsler Individual Achievement Test (WIAT) were examined in a heterogeneous neuropsychological sample of 298 children aged 6 to 16 years. Cluster analysis was applied to a split-half sample of selected WIAT subtests to examine the sample for underlying patterns of academic performance. Four distinct and reliable WIAT pattern subtypes were identified. These subtypes included (1) global academic deficits, (2) better performance on tasks of mathematical ability relative to reading and spelling, (3) better performance on tasks of reading and spelling relative to mathematics, and (4) average performance on all tasks. These WIAT subtypes had been previously reported in cross-cultural literature, utilizing clinical and statistical methodologies with the Wide Range Achievement Test (WRAT) (e.g., van der Vlugt & Satz, 1985).Item Hierarchical cluster analysis of formal personality theorists: An empirical designation of theoretical families(Wichita State University, Department of Psychology, 2006) Cramer, Kenneth M., 1967-; Collins, Kandice R.The emphasis, de-emphasis, or no emphasis of 20 dimensional categories (e.g., unconscious processes, purposive behaviour, early development) were compared by hierarchical cluster analysis for 15 formal personality theorists (e.g., Freud, Rogers, Bandura). Results uncovered three relatively unique families of theorists with 100% reclassification: (a) Adler, Erikson, Freud, Horney, and Murray were grouped as Neo/Freudians; (b) Allport, Bandura, Jung, Kelly, and Rogers as Phenomenologists; and (c) Cattell, Dollard/Miller, Eysenck, and Skinner as Empiricists. The first of two discriminant functions was based on positive loadings from each of purposive behaviour, multiple motives, and self-concept; and successfully discriminated among all three clusters (Neo/Freudians exceeded the Phenomenologists who exceeded the Empiricists). The second function was based on positive loadings from each of developmental continuity, early development, and learning; and negative loadings from purposive behaviour, uniqueness, organismic focus, and ideal self. This function successfully discriminated between the Phenomenologists and both Empiricists and Neo/Freudians (who did not differ).Item Organizational cultures across national boundaries: Results of a cluster analysis(Wichita State University, Department of Psychology, 2006) Kwantes, Catherine T.; Boglarsky, Cheryl A.The recent increase in global business has resulted in new challenges for organizations. One of these challenges is to create a strong global culture while simultaneously adapting to local cultural expectations. This research explored how both globalization and local adaptations of organizational cultures may coexist by using cluster analysis. Organizational culture data were used to cluster organizations from ten different nations: Australia, Canada, Germany, Hong Kong, Italy, New Zealand, Singapore, South Africa, the United Kingdom and the United States. Two solutions were generated using hierarchical clustering. In the first solution, four clusters emerged, but two of them were single item clusters (organizations in Germany and South Africa). Following recommended procedure, organizations from these countries were removed from analysis and the cluster analysis was rerun. Two main clusters then emerged: one with Asian countries, and one with European, North American, and Australasian countries. Cluster profiling suggests that significant differences between the clusters were found in each of the organizational culture aspects used to form the cluster variate.
