This study compared the relative accuracy of (a) single Occupational Scale (OS) scores on the Strong Interest Inventory (SII) and (b) multiple-predictor scoring functions for discriminating members of nine occupations from people-in-general. The functions were constructed using discriminant function analysis with 4797 adults drawn from criterion…

Item bias is a major threat to measurement validity. Methods for detecting differential item functioning (DIF) are now commonly used to identify potentially biased items. DIF detection methods for dichotomous items are well developed, but those for ordinal items are less well developed. In this article, the authors compare four methods for…

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…

Cluster analysis identified 3 groups of individuals who differed systematically on attributions of relative importance to work and to family roles. Participants were 213 married computer workers and lawyers, 126 men and 87 women. Questionnaires gathered data on attributions of importance to life roles, work-family conflict, spousal and managerial…

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 present study examined whether school psychologists who serve a single school ("In-House" group) differed from school psychologists who serve several schools concurrently ("Traditional" group) in the three areas of job satisfaction, burnout, and effectiveness as perceived by the school psychologist. A total of 63 school psychology…

Four identity dimensions (Commitment Making, Identification with Commitment, Exploration in Depth, and Exploration in Breadth) were used to derive identity statuses by means of cluster analysis in a sample of late adolescents. This strategy resulted in both a qualitative refinement and a quantitative extension of Marcia's (1966) model. Five…

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…

The purpose of this study was to explore how satisfied prospective science teachers are with their department (academic staff and administration) at different Faculties of Education in Turkey. For this purpose, Prospective Science Teachers Satisfaction Questionnaire (PSTSQ) was developed by considering related literature. PSTSQ consists of two…

This study aims to explore the utility of the resilient, overcontrolled, and undercontrolled personality prototypes in discriminating adolescents with respect to their academic and social functioning and success. One-hundred and twelve male and 95 female Italian adolescents (mean age = 17 years old) participated in the study and filled out a…

The study investigates the effect of length of meditation history on various factors, namely learning motivation, learning outcome and classroom climate. Data were collected from working adult learners (n = 450) attending meditation classes in two large cities in Taiwan. The investigation categorized learners based on meditation experience, namely…

The purpose of this study was to investigate Korean children's environmental literacy levels and the variables that affect their environmental literacy. An instrument, the Environment Literacy Instrument for Korean Children (ELIKC), was developed that measures four different dimensions (knowledge, attitude, behaviour, and skills) using 69 items…

The control of human limb movement has been the focus of research for more than a century. A major issue to emerge from this work is the manner in which the central nervous system regulates electromyographic (EMG) activity to produce movements that differ in distance, velocity, and movement time. However, the different methods of analysis often…
