A surprising validation of expectation experienced during a recognition test induces the perception of discrepancy and a feeling of familiarity. The authors investigated whether that perception also affects memory performance when it is experienced in the original encounter with a stimulus. Target words were presented in a study phase, half in…

Any programme of principal induction must find ways to respond to the diversity of its participants, in terms of their backgrounds and learning needs. New Zealand's national principal induction programme uses a self assessment of each principal's capability in the leadership of teaching and learning as one of its main sources of information about…

In this study we investigated the putative role of cognitive dysfunction, diagnosis (schizoaffective versus schizophrenia disorder), and alcoholism as risk factors for suicidal behavior among individuals with DSM-IV schizophrenia or schizoaffective disorders. Subjects received cognitive tests and medical records were reviewed for evidence of a…

Propensity score analysis is one statistical technique that can be applied to observational data to mimic randomization and thus can be used to estimate causal effects in studies in which the researchers have not applied randomization. In this article the authors (a) describe propensity score methodology and (b) demonstrate its application using…

The use of canonical analysis and multiple discriminant analysis to analyze equity-parity in colleges and universities is assessed and distinguished from multiple regression analysis. Multiple regression analysis forces the variable weights throughout the salary structure to be uniform, permits only one criterion or dependent variable to be…

To ascertain differences in cognitive ability, 50 monolingual and 50 bilingual Hispanic children enrolled in the same remedial education program for preschool four-year-old children in a large, urban school district in Arizona were administered the Cooperative Preschool Inventory in English. Subjects were matched on the basis of total scores to…

According to organizational theory, the administrative structure of schools has an effect on the feasibility and ease of improving their operation. To determine whether schools are better characterized as rational bureaucracies or as loosely coupled systems or whether some schools belong to each model, four dimensions were operationalized (goal…

The relationship of multiple linear regression to various multivariate statistical techniques is discussed. The importance of the standardized partial regression coefficient (beta weight) in multiple linear regression as it is applied in path, factor, LISREL, and discriminant analyses is emphasized. The multivariate methods discussed in this paper…

The nature and appropriate application of the technique of multivariate analysis are discussed. More specifically, the intent of the paper is to demystify and explain the use of multivariate analysis as well as provide guidelines for selection of the most effective statistics for use in specific situations. For the purpose of this paper, the term…

Two factor analytic studies of anxiety and locus of control produced multiple factors in groups of normal and non-normal children. Mean scores discriminated between groups and the factors that emerged differed qualitatively across groups. The multidimensionality of the constructs and qualitative differences as these constructs operated in the…

Research attempted to establish the existence or lack of existence of an identifiable "rural culture" and to establish the presence or absence of an equivalence relationship between geographic residence and rural culture. A factor analysis of a wide range of attitudinal questions from the 1977 National Opinion Research Center (NORC)…

Predicting occurrences of violent behavior in the population of emotionally disturbed criminal offenders was investigated by identifying a pattern of characteristics that significantly discriminates between violent and nonviolent offenders. Subjects were 149 current and former male patients in the Forensics Division of St. Elizabeths Hospital in…

A U.S. Air Force study was designed to investigate simultaneously four cognitive styles--field dependence-independence, reflectivity-impulsivity, leveling-sharpening, and visual-haptics. A sample of 206 undergraduate volunteers at the University of Oklahoma were tested with the Successive Perceptual Test I (SPT-I), the Hidden Figures Test (HFT),…

THE PURPOSE OF THIS ANALYSIS WAS TO DISCOVER CERTAIN ASPECTS OF STYLE (BOTH LEXICAL AND GRAMMATICAL) WHICH COULD BE COUNTED AND WHICH WOULD, WHEN COMPARED, DIFFERENTIATE BETWEEN THE WRITTEN PROSE OF TWO AUTHORS. THE SUBJECT SELECTED FOR ANALYSIS WAS "THE O'RUDDY," BEGUN BY STEPHEN CRANE AND COMPLETED BY ROBERT BARR. SINCE THERE WAS NO…

This study was concerned with various schemes for reducing the number of variables in a multivariate analysis. Two sets of illustrative data were used; the numbers of criterion groups were 3 and 5. The proportion of correct classifications was employed as an index of discriminatory power of each subset of variables selected. Of the four procedures…
