The use of Bayes' estimates for proportions in the Law of Comparative Judgment is suggested to avoid sample proportions of zero and one. (Author)

Examines the kind of analysis performed for material on the job prospects in the Occupational Outlook Handbook and evaluates the accuracy of previous projections. Discusses why projections of job outlook are made, methods used in their development, and their accuracy. (JOW)

A variety of methodological and statistical problems in the Roffe and Bryant study of the McCarthy Scales' profile reliability are pointed out. Alternative procedures and more efficacious use of the Roffe and Bryant data are suggested. (Author)

The procedures yielding confidence intervals for maximized alpha coefficients of Joe and Woodward are reviewed. Confidence interval procedures of Whalen and Masson are next reviewed. Results are then presented of a Monte Carlo investigation of the procedures. (Author/CTM)

Near-infrared spectroscopy is currently used to assess changes in the oxygen saturation of the muscle during exercise. The primary purpose of this study was to assess the reliability of near-infrared spectroscopy in determining muscle oxygen saturation (StO[subscript 2]) in the vastus lateralis during cycling and the gastrocnemius during running…

The aim of this study is to investigate the effects of emotion strengthening as a training programme for optimism for nurses. The experimental and control group of this research was totally composed of 20 nurses. A pre-test post-test research model with control group was used in this research. Nurses' optimistm levels have been measured by…

The problem addressed in this study was that little was known about the impact on student academic achievement, when grouped by learning style, in a multiple intelligence based science curriculum. The larger problem was that many students were frequently unengaged and, consequently, low achieving in their science courses. This quantitative study…

This study examines how feedback interest after career assessment can be influenced by changing individuals' beliefs about the importance and modifiability of the various performance dimensions. In an experiment, 82 master students completed a computerized assessment tool developed for assessing managerial potential. Results showed that…

A renewed focus on foreign language (FL) learning and speech for communication has resulted in computer-assisted language learning (CALL) software developed with Automatic Speech Recognition (ASR). ASR features for FL pronunciation (Lafford, 2004) are functional components of CALL designs used for FL teaching and learning. The ASR features…

A practical application of generalizability theory, demonstrating how the variance components contribute to understanding and interpreting the data collected to evaluate a program, is described. The evaluation concerned 120 learning modules developed for the Dental Auxiliary Education Project. The goals of the project were to design, implement,…

The purpose was to examine psychosocial factors that influence the physical activity behaviors of adults with brain injuries. Two differing models, based on Harter's model of self-worth, were proposed to examine the relationship between perceived competence, social support, physical self-worth, affect, and motivation. Adults numbering 384 with…

This paper presents three different ways of computing the internal consistency coefficient alpha for a same set of data. The main objective of the paper is the illustration of a method for maximizing coefficient alpha. The maximization of alpha can be achieved with the aid of a principal component analysis. The relation between alpha max. and the…

Estimates for the variances of empirically determined scoring weights are given. It is also shown that test item writers should write distractors that discriminate on the criterion variable when this type of scoring is used. (Author)

The professional orientation difference approach was operationalized as a stress on the importance of intellectual activity, autonomy, service and influence, with de-emphasis on the monetary, prestige, security and human relations aspects of a job. As a difference score, the index was subject to special reliability problems. This analysis…

This investigation dealt with the development and evaluation of both a music dictation test (PRM78 Dictation Test) and a sightsinging test (CSS76 Criterion Sightsinging Test). It was hoped that the dictation test could eventually be developed to serve as an adequate replacement for the latter. Thirteen samples participated in this project--7…
